Comment 6 for bug 570589

Jeremy,
There's no upstream bug as this is not exactly a bug per definition, it's more like a new feature that's being worked on. I don't think it'd be a good idea to file a bugreport upstream either as this is already under development.
If you want you may consider this "bug" fixed upstream and we can mark this fixed in Ubuntu as soon as 2.6.34 hits the archives and the radeon-kms.conf is altered so powermanagement is being used. Which reminds me that we should add the package responsible for radeon-kms.conf to this bug too, but I have no idea which package that might be (the package-search on packages.ubuntu.com comes up empty).

I will keep a watch on this during the development of 10.10 so we can address this properly once the right packages are in the archives.
