Bummer, I've been reading the logs a bit too quickly. It seems we have
two different problems here:

2.6.30-1-64smp doesn't boot (apparently doesn't load init, hangs after
the badness in smp.c message)
2.6.30-1-64up crashes while loading PCI drivers

A log of the up kernel with pdcchassis=3D0 would thus be helpful.
