      To satisfy an idle curiosity, I installed <a
      href="http://www.lesswatts.org/projects/powertop/">PowerTOP</a> on my
      Zaurus to see how many wakeups a second it was doing.  It started out at
      112w/s, which isn't that great, but Richard told me that I should give our
      2.6.24-rc8 kernel a go, because it has <tt>NO_HZ</tt> defined.  To our
      surprise it booted, and to cut a long story short my Zaurus is currently
      idling at <strong>5.4</strong> wakeups per second, and 11% of those are
      about to be patched out of the kernel.
