When it oopsed, the kernel modesetting oops-on-framebuffer thing happened, and the box wedged solid for about a minute. Then it woke up, and I was able to ctrl-f1 back to my X session to capture the dmesg. The stuff that follows the oops looks quite disturbing, but I think it's from hanging with interrupts off for a minute.
