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)

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.
