And linux as well :)

Well as I said, some ppl have ported some x86 emulation code to linux,
so it's doable to say take the bochs core or something...
probably not worth it though.

But that's also a reason to not give up avoiding the use of BIOS calls
in other drivers, because that might not work everywhere...
