Is there a good reason for that? 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.
