Specifying apci=off in grub seems to have worked. Now I've booted with 
pci=noacpi, and so far it seems to be working. I'll let it run overnight 
with the X screensaver on to see if it cares to lock up. Then I'll try 
the nolapic and noapic options. Then I'll figure out what to try next.

I looked in the BIOS but did not see any options for fine tuning timing 
or slices. I'll look again next time I reboot. How should I manipulate 
slices or timing if I find that capability? And no, I'm not 
overclocking, at least not intentionally :).

Thanks for the questions. Please keep them coming.
