i ran into this problem as well on a Lenovo Thinkpad T510 with nVidia NVS 3100M (rev a2) graphics.
I've run into this problem four or five times in the week that i've owned the laptop. in this particular case the freeze occurred after the screen saver locked the screen, and i entered my password. entering my password unlocked the screen, but that was the last thing i could type or click on.
here's the info from the tail of Xorg.0.log.old (grabbed after a reboot):

[mi] EQ overflowing. The server is probably stuck in an infinite loop.
