Alan,
unfortunately, to mu knowledge Nvidia don't use Launchpad to work their bugs. I think it is very odd that the graphics card driver is causing this, but i can't fault your testing results. Did you get the opportunity to try an upstream kernel? I'm putting this forward to be reviewed by a member of the Kernel Team to see if we can get you further in defining this issue.
