2.4.18-pre3+preempt, AthlonXP/KT266A

The below oops seems to happen randomly while in XFree86 (4.1.0), generally after several hours of X running. I have a VIA KT266A motherboard + Athlon XP. I'm running Debian sid with 2.4.18-pre3 + Robert Love's preempt patch.

I'd be happy to provide any other pertinent information. Please CC me in replies as I'm not subscribed. Thanks!
