I've encountered similar problems with an Intel D845GBV system. The system is not mine and I didn't have a lot of time to test. Initially the system seemed fine but I was having problems with Compiz and RDC (couldn't switch back from full screen) so I disabled AIGLX in xorg.conf (probably not the best method) and then the problems started. I tried monitoring via ssh and a serial console but when X dies the system locks hard and neither responds. I did try using gdb but it developed an error and reported the data was not reliable. Logs and info attached but the X log only reports "Fatal server error: lockup".
