(Get the code!)
I have the same issue on Intrepid with GM965/GL960 (X3100) hardware and blank screen saver. I manage to get this bug happening when I lock the screen.
Compiz appears to have problems when it switches desktops. That causes compiz.real process to spin at 100% CPU. Although the symptoms of this bug is X running consuming 100% CPU I think we need to eliminate compiz as the cause. There is a desktop switch when the screensaver is switched out. I've had the same symptoms occur when using rdesktop in full screen mode and I go to switch back to windowed mode.
Another behaviour of compiz consuming 100% is ALT+SYSREQ (PRTSCR key) successfully switches off raw keyboard mode in X. This allows a switch to TTY1 using CTRL+ALT+F1. This is not possible when X is using 100%.
Since i've not found anyone else making progress with this bug i'll try to move things forward a little. Could you all report the following information:
* Does ALT+PRTSCR enable tty switching for you (might need to use ALT+SYSREQ+R)?
* Does the bug occur with compiz disabled/
