Owners of GeForce 600 Series graphics cards should be forewarned that the
Nvidia Tesla 470 driver release may result in a crashed installation. This can
occur with the Debian Tesla driver package or the nvidia-installer. I suffered
crashes using both methods. Not all old GeForce cards are affected. I'm back on
nouveau for now. My next graphics card will be AMD. It would be useful to
monitor which Kepler Nvidia cards are a problem, and eventually update the
Tesla 470 package description to list either all cards that work, or all cards
that don't work with Nvidia Tesla 470.
