Title:
  Toshiba NB100 CPU stepping (frequency scaling) does not work

Status in “linux” package in Ubuntu:
  Invalid

Bug description:
  I have a Toshiba NB100 netbook (Intel Atom N270 CPU) and my processor
  is always running at 0.8GHz even when it is under load. The last
  kernel version that worked appropriately on my netbook was the
  2.6.32-24 kernel in Lucid. All the newer kernel versions seem to be
  affected by this bug - I've tested newer Lucid kernels, the Maverick
  kernels, and the latest kernel in Natty Alpha 3 (2.6.38-5).

  This problem is especially annoying because Toshiba NB100 is an Ubuntu certified netbook: www.ubuntu.com/certification/hardware/200901-1471
