Title:
  AMD Turbo Core not working on 11.10

Status in The Linux Kernel:
  Unknown
Status in linux package in Ubuntu:
  Invalid

Bug description:
  The kernel says: 
  $ dmesg | grep powernow
  [    1.877385] powernow-k8: Found 1 AMD Phenom(tm) II X6 1100T Processor (6 cpu cores) (version 2.20.00)
  [    1.877398] powernow-k8: Core Performance Boosting: on.
  [    1.877423] powernow-k8:    0 : pstate 0 (3300 MHz)
  [    1.877424] powernow-k8:    1 : pstate 1 (2500 MHz)
  [    1.877425] powernow-k8:    2 : pstate 2 (1700 MHz)
  [    1.877426] powernow-k8:    3 : pstate 3 (800 MHz)

  But when I'm running a singe threaded application, cpuinfo says: 
  $ cat /proc/cpuinfo | grep MHz
  cpu MHz		: 800.000
  cpu MHz		: 3300.000
  cpu MHz		: 800.000
  cpu MHz		: 800.000
  cpu MHz		: 800.000
  cpu MHz		: 800.000

  when I should be getting a boost to 3700MHz.
