-+	  display and keyboard devices. These are called "virtual" because you
-+	  can run several virtual terminals (also called virtual consoles) on
-+	  one physical terminal. This is rather useful, for example one
-+	  virtual terminal can collect system messages and warnings, another
-+	  one can be used for a text-mode user session, and a third could run
-+	  an X session, all in parallel. Switching between virtual terminals
-+	  is done with certain key combinations, usually Alt-<function key>.
-+
-+	  The setterm command ("man setterm") can be used to change the
-+	  properties (such as colors or beeping) of a virtual terminal. The
-+	  man page console_codes(4) ("man console_codes") contains the special
-+	  character sequences that can be used to change those properties
-+	  directly. The fonts used on virtual terminals can be changed with
-+	  the setfont ("man setfont") command and the key bindings are defined
-+	  with the loadkeys ("man loadkeys") command.
-+
-+	  You need at least one virtual terminal device in order to make use
-+	  of your keyboard and monitor. Therefore, only people configuring an
-+	  embedded system would want to say N here in order to save some
-+	  memory; the only way to log into such a system is then via a serial
-+	  or network connection.

-+	---help---
-+	  The frame buffer device provides an abstraction for the graphics
-+	  hardware. It represents the frame buffer of some video hardware and
-+	  allows application software to access the graphics hardware through
-+	  a well-defined interface, so the software doesn't need to know
-+	  anything about the low-level (hardware register) stuff.
-+
-+	  Frame buffer devices work identically across the different
-+	  architectures supported by Linux and make the implementation of
-+	  application programs easier and more portable; at this point, an X
-+	  server exists which uses the frame buffer device exclusively.
-+	  On several non-X86 architectures, the frame buffer device is the
-+	  only way to use the graphics hardware.
-+
-+	  The device is accessed through special device nodes, usually located
-+	  in the /dev directory, i.e. /dev/fb*.
-+
-+	  You need an utility program called fbset to make full use of frame
-+	  buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
-+	  and the Framebuffer-HOWTO at
-+	  <http://www.tahallah.demon.co.uk/programming/prog.html> for more
-+	  information.
-+
-+	  Say Y here and to the driver for your graphics board below if you

-+	  can run several virtual terminals (also called virtual consoles) on
-+	  one physical terminal. This is rather useful, for example one
-+	  virtual terminal can collect system messages and warnings, another
-+	  one can be used for a text-mode user session, and a third could run
-+	  an X session, all in parallel. Switching between virtual terminals
-+	  is done with certain key combinations, usually Alt-<function key>.
-+
-+	  The setterm command ("man setterm") can be used to change the

-+	  man page console_codes(4) ("man console_codes") contains the special
-+	  character sequences that can be used to change those properties

-+	  with the loadkeys ("man loadkeys") command.

-+	  You need at least one virtual terminal device in order to make use

-+	depends on VT
-+	---help---
-+	  The frame buffer device provides an abstraction for the graphics
-+	  hardware. It represents the frame buffer of some video hardware and
-+	  allows application software to access the graphics hardware through
-+	  a well-defined interface, so the software doesn't need to know
-+	  anything about the low-level (hardware register) stuff.
-+
-+	  Frame buffer devices work identically across the different
-+	  architectures supported by Linux and make the implementation of
-+	  application programs easier and more portable; at this point, an X
-+	  server exists which uses the frame buffer device exclusively.
-+	  On several non-X86 architectures, the frame buffer device is the
-+	  only way to use the graphics hardware.
-+
-+	  The device is accessed through special device nodes, usually located
-+	  in the /dev directory, i.e. /dev/fb*.
-+
-+	  You need an utility program called fbset to make full use of frame
-+	  buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
-+	  and the Framebuffer-HOWTO at
-+	  <http://www.tahallah.demon.co.uk/programming/prog.html> for more
-+	  information.
-+
-+	  Say Y here and to the driver for your graphics board below if you
-+	  are compiling a kernel for a non-x86 architecture.

-+	  want to play with it, but it is not essential. Please note that

-+	---help---
-+	  If you say Y here, you will get support for terminal devices with
-+	  display and keyboard devices. These are called "virtual" because you
-+	  can run several virtual terminals (also called virtual consoles) on
-+	  one physical terminal. This is rather useful, for example one
-+	  virtual terminal can collect system messages and warnings, another
-+	  one can be used for a text-mode user session, and a third could run
-+	  an X session, all in parallel. Switching between virtual terminals
-+	  is done with certain key combinations, usually Alt-<function key>.
-+
-+	  The setterm command ("man setterm") can be used to change the
-+	  properties (such as colors or beeping) of a virtual terminal. The
-+	  man page console_codes(4) ("man console_codes") contains the special
-+	  character sequences that can be used to change those properties
-+	  directly. The fonts used on virtual terminals can be changed with
-+	  the setfont ("man setfont") command and the key bindings are defined
-+	  with the loadkeys ("man loadkeys") command.
-+
-+	  You need at least one virtual terminal device in order to make use
-+	  of your keyboard and monitor. Therefore, only people configuring an
-+	  embedded system would want to say N here in order to save some
-+	  memory; the only way to log into such a system is then via a serial
-+	  or network connection.

-+	bool "Support for frame buffer devices"
-+	depends on VT
-+	---help---
-+	  The frame buffer device provides an abstraction for the graphics
-+	  hardware. It represents the frame buffer of some video hardware and
-+	  allows application software to access the graphics hardware through
-+	  a well-defined interface, so the software doesn't need to know
-+	  anything about the low-level (hardware register) stuff.
-+
-+	  Frame buffer devices work identically across the different
-+	  architectures supported by Linux and make the implementation of
-+	  application programs easier and more portable; at this point, an X
-+	  server exists which uses the frame buffer device exclusively.
-+	  On several non-X86 architectures, the frame buffer device is the
-+	  only way to use the graphics hardware.
-+
-+	  The device is accessed through special device nodes, usually located
-+	  in the /dev directory, i.e. /dev/fb*.
-+
-+	  You need an utility program called fbset to make full use of frame
-+	  buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
-+	  and the Framebuffer-HOWTO at
-+	  <http://www.tahallah.demon.co.uk/programming/prog.html> for more
-+	  information.
-+
-+	  Say Y here and to the driver for your graphics board below if you
-+	  are compiling a kernel for a non-x86 architecture.
-+
-+	  If you are compiling for the x86 architecture, you can say Y if you
-+	  want to play with it, but it is not essential. Please note that
-+	  running graphical applications that directly touch the hardware
-+	  (e.g. an accelerated X server) and that are not frame buffer
-+	  device-aware may cause unexpected results. If unsure, say N.
