hehe.... I feel your pain. After working through various distros, trying to get them to work, redhat was the first one that my limited knowledge and the install procedures jelled together, and it worked (almost) flawlessly..I have a geoforce also, not exactly the same specs, but I had no issues...

Deferring back to Mittens, what is the error you are getting? Are you using the custom install, or automatic?
