In fact my dell notebook is also an intel core2 duo 64bit system.
Additionally to the keyboard and mouse lockups, my X11-Sessions thend to
crash from time to time. I have spent some hours analysing the log files
but the only thing I found is the following message from X11 which
appears after the Xserver crashed:
==> Xorg.0.log <==

My Graphic card is an integrated intel 945GM express using the i810 X11
driver. The system seems to run stable as long as I do not use the
keyboard, the touchpad or the mouse. As soon as I use one of these
devices I experience random X11-crashes.
I am still trying to find out further details.
