This is kind of gross and not really tested much (it boots on 2 of my
PPC boxes a quad G5 and a PB G4), but it does compile.

I stubbed out most of the functions that were missing, I don't think the
functions are actually being called anyway.

Hope this helps to at least push the conversation in the right direction,
