I have same identical problem with my Dell laptop (intel 810 based card). When I upgraded Feisty to Gutsy I get in trouble with this problem (about one month ago) and I still have it.
I found only one method to always reproduce it otherwise it is very random (and of course only with compiz enabled (I use metacity not emerald)): - open AWN (avant-window-navigator) - then try to drag&drop an icon in the awn bar - freeze Same identical issues when it crashes, all the screen is freeze but mouse still works, no way to close X server or to switch in console.
