Kernel hosed or Nvidia modules?

Is that a genuine kernel bug (2.4.19-pre2-ac3 here) or Yet Another
Nvidia Driver Bug (would not be the first bug to bite me in their
driver)? The Nvidia driver is configured to use the kernel AGP rather
than the Nvidia AGP. (TNT board, FWIW).

This does not happen frequently. Does anyone have a contact address at
Nvidia so I can show them as well?
