Since posting, I have had freezes both with and without the mouse cursor still able to move. Usually, the mouse cursor is still able to move, and usually I am able to reboot with alt+sysrq rseiub. My uptime is basically unlimited with effects turned off. Since I've used Compiz for over a year without this problem, my best guess is that the bug that I am experiencing is located within the new version of X in Gutsy. I wish I could help pin it down more though.
