I can confirm what spinkham wrote. I got the problem only with the restricted nvidia driver. No problems with the free one.
Ubuntu 8.04 64 bit
Dell M1530
01:00.0 VGA compatible controller: nVidia Corporation GeForce 8600M GT (rev a1) (prog-if 00 [VGA controller]) Subsystem: Dell Unknown device 022e
