Ohhh, I didn't even notice ohw.diff in pc-bios/ despite looking for
one!
I'll try to dig that one on gmane.org.

I just hope it's easier to build than OpenBIOS...

I tried building it for PPC yesterday, but I only had an powerpc-apple-
haiku- gcc around, and it didn't like it... Even after pointing it to
find our stdint.h and endian.h (WTF does it need OS headers to build a
BIOS ???).
It seems to be doing nasty things with m4 macros on C headers, really
ugly.

CoreBoot actually supports more arch than just x86:

But only v1 seemed to have ppc support.
