Fedora 15 + AMD 6950 graphics = Gnome 3 Fallback mode plus loud fan

[Jeff72]

Any ideas on how to enable the Gnome Shell with an AMD 6950 graphics card and the default Fedora 15 drivers?

I may try the AMD Catalyst proprietary drivers but from history those usually lag behind the Fedora versions. I also read some people had issues with the current AMD Catalyst drivers in the Catalyst guide thread.

Also, the AMD 6950 graphics card fan is at full speed all the time in Fedora 15. Any suggestions on controlling that? I do believe you can with the Catalyst drivers using aticonfig but was wondering about the default Fedora 15 drivers?
