My attention was dragged onto this post because I have similar problems also with SL 10.1 on an ASUS A6JM Notebook (Geforce go 7600). However, it was dosbox that caused freezes right after startup (just after the window was created, and you can see a black window without contents - openGL is used to render on it) on a random basis.
From a remote ssh-login I could still examine what's going on though. dmesg shows

X process was at 100% and oprofile showed where it actually stuck:

The name is obviously of no use to me.
After reading this thread I thought the problems are related so I installed houdini and what I got was even worse. Right after opening a larger file in mplay it not only gets stuck for a few seconds, after that "something" is shown and after some window resizes parts of the picture are "scattered" over my desktop (and even remain there after closing mplay). Note that i wasn't even doing the "f"-key trick yet.
Even though my problem seems worse than the one of the thread starter I still think its the same problem. I mean it always has to do with creating/resizing of some window (which also remains true for my initial problem)
PS: I'm using driver 1.0-8762
I don't think it's neccessary to post the nvidia-bug-report.log
