Unless you port the XFree86 bios interpreter to work on powerpc or
something such. I think some experiments where already made, but i don't
know if it is conclusive. The idea is to have the int10/vbe/whatever it
is read the bios, and then pass it to an x86 emulator to execute it and
intialize the card.
