I don't know as debug this problem, but the same occurs to my machine
after one day or two of uptime the X windows freeze,

- no errors are reported in the logs (messages, dmesg , Xorg.log),
- but the keyboard is dead as the mouse clicks
- the machine is accesible via ssh to shutdown ( restart it)

the solution which works for me is disable the desktop effects in KDE,
after that no more lockups.

this with Fedora 11 x86_64 KDE 4.3( ocurred with 4.2 too) with a

00:02.0 Intel Corporation 82G33/G31 Express Integrated Graphics
Controller (rev 02)
