++ *
++ *  	Set a single color register. The values supplied have a 16 bit
++ *  	magnitude which needs to be scaled in this function for the hardware.
++ *	Things to take into consideration are how many color registers, if
++ *	any, are supported with the current color visual. With truecolor mode
++ *	no color palettes are supported. Here a psuedo palette is created
++ *	which we store the value in pseudo_palette in struct fb_info. For
++ *	pseudocolor mode we have a limited color palette. To deal with this
++ *	we can program what color is displayed for a particular pixel value.
++ *	DirectColor is similar in that we can program each color field. If
++ *	we have a static colormap we don't need to implement this function.
++ *
++ *	Returns negative errno on error, or zero on success. In an
++ *	ideal world, this would have been the case, but as it turns
++ *	out, the other drivers return 1 on failure, so that's what
++ *	we're going to do.
