Any dual processor machine is going to use the SMP kernel (and there's a lot of dual processor G4's out there...), and any single processor machine needs the non-smp kernel, right?  So, wouldn't dropping any of them mean dropping support one of following:  single processor machines, SMP support, or 64-bit support.

The SMP kernel will run on a single CPU with a (alleged) slight performance hit.  I can't see any obvious problem on a single CPU with the SMP kernel.  I'm sure if somebody ran the Phoronix Test Suite to compare them, some difference would show up.
