Comment 2 for bug 458163

I think this is pretty critical, as this functionality has been working for almost all of Karmic.

And it was featured rather prominently in Mark's Karmic announcement:

  "A savvy Koala knows that the best way to conserve energy is to go
  to sleep, and these days even servers can suspend and resume, so imagine
  if we could make it possible to build a cloud computing facility that
  drops its energy use virtually to zero by napping in the midday heat,
  and waking up when there's work to be done. No need to drink at the
  energy fountain when there's nothing going on. If we get all of this
  right, our Koala will help take the edge off the bear market."
