Strange failure, probably video card

[Kevin O'Gorman]

Kernel is 2.8.0-31-generic SMP x86_64 (amd 4-core)
I don't think it's the driver because I have had this card for several
years, but the log messages started just a week or so ago.
However, I'm not sure how to even tell what driver I'm using, and I
fool around with many things on this machine -- I don't remember what
i did about drivers.
It may help to know that among the installed packages are
  nvidia-304
  xserver-xorg-video-nouveau
  nvidia-settings-304
