I'm interested in more complete PCBIOS functionality, like ADLO,
rather than something just for running option ROMs. 
(Running LILO in an emulator wouldn't be really useful!)

I'm thinking on possibility of implementing BIOS *services* in
real mode, and initialization (POST), including option ROM 
handling, in 32-bit.

Services can be written in normal C. They will be built into a realmode
SystemBIOS image when built for x86, and for non-x86, they will be
compiled natively and linked together with x86 emulator.
Only entry/exit routines (to/from 16-bit code, eg. VGABIOS) will
make the difference.
