Kernel 3.11.0-1.4 (based on the upstream 3.11-rc4 kernel) is now
available in Ubuntu 13.10 Saucy Salamander. Also, kernel 3.11.0-2.5 is

has some bugfixes for the new DPM method.

I neglected to mention that to use the new power management feature on R700 and
newer hardware (other than APUs) requires installation of the latest AMD

Better power management for AMD/ATI Radeon R600 and newer hardware is
finally available in the upstream 3.11 linux kernel. The first release
candidate (3.11-rc1) of the 3.11 kernel is available at
http://kernel.ubuntu.com/~kernel-ppa/mainline/ and instructions on how

Your most recent comment describes a well known disparity between power
management in the open-source Radeon driver and power management in the
closed-source Catalyst (fglrx) driver. There is probably not much you

Anything I can help test?
