I am experiencing the same bug with a Lenovo SL500, NVIDIA GeForce G 105M with the NVIDIA binary driver under Unity - I haven't tested classic. The touchpad worked fine in Ubuntu 10.10 (and still works fine under windows 7). If I don't move the pointer at all, but continue to click it doesn't start working again. Usually clicking only stops working for a second or so if I'm moving the pointer.
In case it's relevant, the system also claims that the NVIDIA binary driver is installed but not in use, but compositing works, the proprietary NVIDIA configuration tool works, and the default Ubuntu monitor configuration tool does not work, so, I'm reasonably sure that the binary driver is being used (this is another bug, but I mention it in case they're related).
