Mark: You'll note that the 9800GT is listed there, too. nevertheless it isn't supported. I was told that current GPU software required a Nividia Fermi or later GPU, which leaves out the entire 9xxx series. See http://nouveau.freedesktop.org/wiki/CodeNames/ Re upgrading to C7, I can see how you may be nervous about that, given the number of things changed. I just upgraded my personal desktop during Christmas week, seeing as how I never rush into upgrading to a new version until it has had time to "settle". There are a lot of differences, but i'm learning to deal with them. When my old system gets old enough that a lot of newer stuff will no longer build, then it's time for me to do the deed. then all I have to do is steel myself up for a week of putting it all back together. :) good luck, Mark!
