Hey, disabling DRI did the trick.  Aside from things being remarkably
slow, it's remarkably stable. ;) Threaded X apps or no, I'm running
a July 19 kernel with no instant reboots.  PREEMPTION disabled,
WITNESS enabled (I misspoke in another message when I said WITNESS was
disabled---apparently I fiddled more than I had remembered).  Toggling
DRI back on and restarting X/kdm reboots immediately.
