OK, that all makes sense, and I agree based on that.  I'd forgotten
about the dual G4 class.

I would switch the installer over to powerpc-smp today, then, except
that the kernel doesn't ship powerpc-smp udebs yet, only powerpc and
powerpc64-smp.  Can somebody fix that so that I can do this transition?
