But there is an #ifdef _powerpc_ so it can't break x86 machines?

Yes but it *does* break x86 cards used in ppc machines.
(linux/ppc isn't the only ppc os supported in xfree and they won't
be happy if we break things for them)

And the int10 or whatever code works for them?

ISA IO/MEM works for them so yes int10/vgahw should be fine there, i think
that linux/ppc is the only platform with this broken (with the new syscalls
we its simple to get it working for machines with one iobase and a working
ISA memory)

And then set info->VBIOS = NULL for OF and change the #ifdef _powerpc_ to if
(!info->VBIOS) or similar?

Right something along this lines will do, you probably need to change the
R128_BIOS16/32 macros to do byteswapping as well since the fields in the rom
are in little endian format.

I have my last exam for this year tomorrow and leave for two weeks of vacation
on Saturday, so I wish good luck to any takers :)

Good luck in your exam, i'll try to write something over the weekend if i
can find some free time.
