Inresting. I started doing that (and updated the pre-ATOM BIOS code too)
but never finished... One thing you could do that would be useful is
move the various BIOS code to separate function and setup function
pointers that can be set based on the BIOS type instead of the endless
stream if (atom_bios) xxx else yyy. That way, it will be cleaner and
I'll be able to more easily add other variations like retreiving infos
from Open Firmware on ppc etc...

Ben.
