I can confirm as well on an HP Pavilion dv6000 with 256MB NVIDIA GeForce 8400M GS (nvidia-glx-new). X freezes, mouse cursor is responsive, clicks and keypresses are non-responsive (can't Ctrl-Alt-Backspace). Logging in via ssh reveals compiz-real at 100%.
No solid repro, but freeze has happened twice while Ctrl-Alt-Arrow switching desktops to a desktop where Firefox has a "do you want to allow this popup" notification waiting. System basically becomes unresponsive as soon as the sliding animation to the next desktop finishes.
