My impression is that the BIOS display type (usually called 'VGA/EGA' /
'mono' or something like that) (see i386/isa/nvram.h:NVRAM_EQUIPMENT)
is only intended as a hint to the operating system.

I think the display driver is supposed to choose (default) colors
based on it.

Perhaps wscons or vga(4) should have a MD hook to get this hint.
