I've noticed that before a hang there seems to be an increase in hard disk activity.
It also might be worth noting that the problem occurs sooner (less than 10 minutes as opposed to 1hr+) if I do not reboot the X server after a crash and if the crash occurs multiple times without resetting the X server, on the third launch it will always corrupt the graphics at the login screen.
