Here's some more information. Mine is very reproducible if I just watch some Adobe Flash videos in Firefox or Chrome. The crash will not happen at a regular time interval, but can be encouraged by changing tabs while watching a video.
Possibly unrelated, but even using the Nvidia setttings tool, I cannot get Precise to stay in Twinview. I'll save the xorg.conf and it will read it. LightDM will use Twinview, but then after logging in it boots me back to a single monitor. Probably a bug of Unity, not the drivers.
