That's what I'm intersted in doing.
Also I felt that doing this in LinuxBIOS core could be wrong direction
for the project, so I posted the first question.
I think Ron's src/extension idea makes a lot of sense.

Yes, that is why I like this code. This can be easily and cleanly
extended, unlike Bochs BIOS.
As Eric pointed out, this approach has drawbacks, with regard to
full compatibility, it still has many advantages over the way
Bochs doing.
