Very interesting idea. Since x86emu does not emulate protected mode
code, that code could not be emulated, but maybe it could be normal
non-emulated C code that is used for initialization and then the 16
bit code could be emulated...
One concern i have is that i would like YABEL to still be a full BIOS
emulator for SLOF, so i dont want to remove any of the BIOS emulation
code... maybe we could find a way to share the code between the two
emulators.. something like libbiosemu??
Then there is the licensing problem... YABEL is BSD licensed, i am
assuming that SEABIOS is GPL? I would like YABEL to always be portable
to SLOF which is BSD licensed as well...

Ah, didnt read far enough ;-) Thats what i meant with the non-emulated
initialization code above...
