I've had similar problems with my W510. Initially on 10.04 I got lockups with binary and nouveau drivers. I then switched to the x-swat nouveau and was stable for a few months.
Last week it started happening again and this week I upgraded to 10.10. Now it happens about 5 times per day.
I know this is not very helpful. If there is specific information that I can get to help, please ask.
