I ran into a similar https://launchpad.net/ubuntu/+source/xserver-xorg- video-nouveauproblem using "Experimental 3D support for NVIDIA cards" on my Macbook Pro running 11.04. I was able to move the mouse but unable to do anything else, including switching to a different virtual terminal. I did not try accessing the computer via ssh, and I just powered off the machine manually. I have attached my Xorg log, which shows the same kind of error as the end of Steveire's log:
