x86: small boot-time changes:
* use memory 0x8c000-0x90000 to avoid trampling the area above
0x90000 -- some bootloaders may leave droppings in that region
* reserve 2kB for vga mode table -- limit of 128 VESA modes could
overflow the original 1kB allocation
* remove unnecessary alignment of trampoline GDT
