Check your current state:

Now you can recheck if your power state changed to the desired one:
cat /sys/kernel/debug/dri/0/radeon_pm_info
Using latest stable 2.6.35.

You need to mount debugfs somewhere, like this :
Code:mkdir /debugfs mount -t debugfs debugfs /debugfs cat /debugfs/dri/0/radeon_pm_info
Well, for me it works...(r7xx, radeon 4550)...but it seems to slow to get back to normal temperature...I mean, even in low mode, the fan need at least 5 minutes to spin down again after playing a video.
And why are the PCIe lanes are always equals to 16 whatever the profile mode...?

Just a question : is development for powersaving features done ? I mean, it still needs improvement, doesn't it ? Still not as good as the catalyst powerplay....

That's a very bad news indeed...so there is no way it would have someday the same behavior as the catalyst driver (without reflashing the bios) ? I mean what if the only way to reduce even more the energy consumption was to reduce the pcie lanes...it must be done somehow by the catalyst driver...or the dynamic clocking algorithm is different...

FWIW I'm currently using fglrx at the moment and it's using all of the 16 pcie lanes with a HD 5750, regardless of the performance level.
