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 graphics microcode (ucode) files to /lib/firmware/radeon
These are available at http://people.freedesktop.org/~agd5f/radeon_ucode/
Get the version ending in "smc".

R700 basically means Radeon HD 4000 series and newer. However note that
according to Wikipedia and
http://xorg.freedesktop.org/wiki/RadeonFeature/#index5h2 the Mobility
Radeon HD 4225/4250 is a RV620 chip, so anyone with one of those
shouldn't need the updated firmware files.

Title:
  Hardware temperature hazardously hot

Status in “linux” package in Ubuntu:
  Fix Committed

Bug description:
  Parts of the notebook computer become painfully hot to the touch while
  running Ubuntu, and the fan is not running.  When I boot back to OS X,
  the fan kicks in and runs until the computer returns to being cool to
  the touch.  What metrics do I need to collect to help fix the problem?

  There seem to be two problems, one is that the hardware near the
  screen (GPU?) getting WAY too hot, another is that the fan is not
  turning on when the hardware gets too hot.

  This is the recent ubuntu:
  $ lsb_release -rd
  Description: Ubuntu 11.10
  Release: 11.10

  This affects the lifespan of the computer and it could conceivably be used to burn out and destroy the hardware very early.
