Hi all,
We consulted Jeremy Kerr about this. He says that an SMP kernel will run
on all 32 bit powerpc platforms, including non-SMP.
To clarify: the hardware supported by the powerpc and powerpc-smp
flavours is almost identical. The differences probably don't matter
Ubuntu users, as it'll be obscure hardware. I've CC-ed benh in case
he wants to correct me on this one.

The main class of 32-bit SMP powerpc machines are the Apple dual-G4s.
So, since the hardware coverage is essentially the same, but we get
SMP support on SMP machines, I'd say that we would prefer the
powerpc-smp kernel over the powerpc flavour.
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?
I'll take care of it. Leann plans to upload later in her day Friday, so
the kernel ought to be available by Monday.
