Yes, how the guest treats those roms is another issue.  bios/efi combo
roms on x86 are not that uncommon.  But I'm not sure how widespread
bios/openfirmare combo roms are used (have been used) in practice.  If
guests can't deal with it (and try to run a x86 emulator on the bios
image instead) it might not be the best plan to go that route.

What does sam460ex use?  Some x86emu fork?  If so upgrading might help.
Xorg uses x86emu too and older versions have problems with the
gcc-generated real mode code too.
