It won't help Thomas87 (knot-tomas) or himynameiskevin (kevinpook), but
proper power management for AMD/ATI Radeon R600 and newer hardware is
finally available in the 3.11 linux kernel.  Ubuntu 13.10 "Saucy
Salamander" is based on the 3.11 kernel and also includes the necessary
updated radeon firmware.  On Saucy, to use this power management for the
AMD/ATI Radeon you will need to select it at boot by adding radeon.dpm=1
to your GRUB kernel boot options as described at
https://help.ubuntu.com/community/Grub2/Troubleshooting#Editing_the_GRUB_2_Menu_During_Boot

See the blog post at http://www.botchco.com/agd5f/?p=57 for further
information.

Unlike the older dynpm method, the new DPM method works with multiple
monitors and there shouldn't be any flickering as the performance level
changes are handled by dedicated hardware rather than the driver.

The currently under-development Ubuntu 14.04 "Trusty Tahr" is based on
the 3.13 kernel which enables DPM by default (without needing the
radeon.dpm=1 boot parameter I mentioned above) for Radeon HD 4000
through Radeon HD 7000 series graphics processors but with some specific
ASICs being excluded. You can download a pre-release version at
http://cdimage.ubuntu.com/daily-live/current/ and the final release is
scheduled for April 17th, 2014 as per
https://wiki.ubuntu.com/TrustyTahr/ReleaseSchedule
