That bug report has a link to this: http://wiki.x.org/wiki/RadeonFeature.
Scroll down to the KMS Power Management Options for a more complete explanation of the options.

Then, do: $ cat /sys/class/drm/card0/device/power_method to check what method you're machine is using
It will very probably answer 'profile'

If so, you can change the content of /sys/class/drm/card0/device/power_profile to low, mid, auto and see what happens. I did that two days ago, and it's worked very well so far.

I haven't modified the necessary config files to make the change persistent through reboots, though. I mean, this method is like putting a ball & chain on your leg to keep you from running, and I'd like to do some experimenting first, perhaps even dynpm, once I understand a bit more of how that might affect things.

Chen: Why do you say it won't be fixed?
