Could you post here the list of available video drivers that you're seeing?
That might help me or somebody else find the best or probable best one for you.
In case you're not too familiar with terminals, in xterm for instance you will just left-click at the beginning of the list and "scroll" down and release the button at the end of it. Then you can probably paste the list in a post here by simply middle-clicking once. If that doesn't work, middle-click in a blank text file and then post the text file here.
Sorry if that's too elementary, but it's something it took me a while to find out when I started using Linux!
