Until arch/ppc is gone... the previous driver works with arch/ppc the
new one with arch/powerpc.

If we kill arch/ppc in .25, then we'll remove the old driver and rename
the new one. If not, that will wait til .26

I'm hard at work porting as much of 4xx over I can to get to the point
where we -can- kill arch/ppc but I'm not done yet.
