oportunity to snitch it while its waiting for a new fan.  Now that I have a
serial console that I can work with here's as far as boot gets with the 1.5
generic kernel:

I imagine that the 'pcid' thing there was longer and actually said
something else but that minicom munged it.  Anyway I don't know much about
debugging this sort of thing, but if anyone wants to point me in a
direction feel free.

"We must be born with an intuition of mortality.  Before we know the words
 for it, before we know there are words, out we come bloodied and squalling
 with the knowledge that for all the compasses in the world, there's only
 one direction, and time is its only measure."		-Rosencrantz
