I have the same problem.
My kernel is newer than 0827, the one around Sep 10.

Graphic card: Matrox G200
arch: i386 (K6-2 300MHz)

If I add something to the above "during some intensive I/O activity",
hangups are very likely to occur when I move mouse during some intensive
disk access (for instance, launching netscape). Also, when I move mouse
aggressively while .xinitrc is executed (in this case disk access is not
so intensive?).
