Tested under 3.0.0-13-generic #22-Ubuntu SMP.  Has identical fan
behavior,  max fan speed is never triggered while kernel is loaded.
Instead machine is severely under-clocked.

** Tags removed: needs-upstream-testing

** Description changed:

  I am running Ubuntu 11.10 on a laptop and the heat management is very
  bad.  The system will heat up and under clock to avoid damage.  When the
  system is restarted and in GRUB the fan speed will go to MAX.  The
  moment the kernel loads the fan speed drops dramatically.    Why not
  increase the fan speed to the max to try and avoid under-clocking?  In
  fact i have never seen my fan speed max out on Ubuntu!  Awful!
  
- Clearly this is incorrect behavior that is not only damaging but severely 
limits the power of the machine.  I will be Channing operating systems until 
this issue is addressed.
