I installed Ubuntu on a second disk and it didn't crash. After a lengthy
process of comparing setups, I think I found the problem.

In xorg.conf, in the monitor section, I was missing the line
Options="DPMS"

I'll still have to research how leaving out this option could lead to
crashes, so I appreciate any insight this group may give.

Michael
