I had a similar issue in 10.5 with the same chipset. Slashack's fix addressed the problem. Since I have not dabbled with 10.6 10.7 on my AMD rig, I could not confirm if it would work for you.

Please see this thread and you may be able to use that information to lead you to a solution. Post back if you are able to solve your problem.
