I'm also having the same issue, using a Dell Latitude e6510 with 280.13 on a NVS3100m. Sometimes it works, and sometimes I get a screen full of artifiacts for about 13 seconds with 2 seconds left to respond to the toast, after which sometimes it seems compiz crashes (with no core left that I can find) with an assertion error somewhere in the boost library.
I'll try to get some more details and attach them.
