For the record, the powerpc-smp kernel doesn't boot AT ALL on my G3
PowerMac.  Doesn't even get far enough to init video of any sort, so
I can't tell you what the problem is.

I'm downloading the source right now, but I have a sneaking suspicion
that, perhaps, our powerpc-smp kernel is built for >= G4 (since that
was the first PPC32 SMP hardware anyone cared about), and thus won't
boot on any older CPUs.
