Do you have any idea why the machine would reboot? I haven't seen any
reboot() functions affixed to randomized timers to parallel Windows'
eat_memory() and corrupt_programs() system calls.

No. Roundabout 1.2 the kernel got pushy enough that my machine goes down
after a few days of uptime no matter what (four days is my record), so
I've kind of resigned myself to the fun. The corruption started around
the VT scrollback rewrite.

My fabulous hardware is Intel Premiere (Gateway) P60, about a year old, a
Cirrus Logic GD-5434 PCI video card, and I even pulled out the old mono
card to make sure that wasn't it. (Interestingly enough, I don't
think the onboard-IDE buffer bug affects me)

I will spend some time with X not running to make sure that it isn't
linked to that.
