Subject: BUG: 2.5.68 fails (sometimes dies) with X/i830 graphic board

The kernel sometime dies at exiting from X with CTRL-ALT-SUP. Sometimes it 
gives errors in the console, something related to mtrr and saying 
"Recovered, but we need to reboot" (sorry, couldn't copy/paste the 
message).

The PC is a Dell Latitude X200, i830M graphic board. DRI is enabled in the 
kernel, but not loaded by X (it works, but I commented it out in 
XF86Config).

In my last try to copy the message, I've got the following error when I 
started X:
