For me with 64bit Ubuntu 6.10 and the 9755 nvidia driver it's quite reproducible.
I've done some testing by just opening new screensaver windows arranging them on the desktop so they are all visible (screensaver is skyrocket) and these are the numbers of seconds I got until PC froze.

Code:
1. 33 seconds, with 3 screensaver windows, until complete freeze
2. 27 seconds, with 5 screensaver windows, until complete freeze
3. 13 seconds, with 3 screensaver windows, until complete freeze
4. 35 seconds, with 7 screensaver windows, until complete freeze
5. 31 seconds, with 7 screensaver windows, until complete freeze
6. 12 seconds, with 2 screensaver windows, until complete freeze
7. 11 seconds, with 2 screensaver windows, until complete freeze
8. 14 seconds, with 3 screensaver windows, until complete freeze
9. 9  seconds, with 2 screensaver windows, until complete freeze
Now, it seems to me that something goes wrong either when a new window is being created whilst we have opengl running or when moving a window around whilst opengl is running.
Twice I stopped opening new ones after I had opened 3 and left it running for 10 minutes with out any problems so it appears it's more likely to happen when creating a new window or moving a window around.
If I don't have the screen saver window open I can open what seems to be an unlimited amount of new windows by pressing "Print Scrn" button.
