Ubuntu 13.10 "Saucy Salamander" is based on the 3.11 kernel and includes
the necessary updated radeon firmware as well.  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

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

Title:
  1002:9612 [HP Pavilion tx2500 Notebook PC] ATI card fan is always on
  with opensource radeon driver

Status in X.org XServer - ATI gfx chipset driver:
  Confirmed
Status in “linux” package in Ubuntu:
  Won't Fix

Bug description:
  $ cat /sys/class/drm/card0/device/power_profile
  low

  When I use the opensource driver for my ATI card the notebook fan is
  always spinning and temperature of outgoing air from fan is very high,
  even when I set /sys/class/drm/card0/device/power_profile to low and
  cpu mode to powersave. With proprietary drivers (fglrx) I set video
  card performance to "ondemand" (I forgot the exact name of this mode
  in ATI control center) and cpu mode to ondemand, and the notebook
  isn't hot, fans are not spinning (if I don't start flash, games or
  some similar app with high cpu load). So with fglrx I can use the
  notebook on battery for 1.5 - 2 hours and it's not hot, but with the
  opensource driver notebook on battery is dead in 50 minutes, the fan
  is always on, it noise is loud, and the notebook is very hot.
