Title:
  move to HZ=100 on non-i386/lpia for efficiency...

Status in “linux” package in Ubuntu:
  Fix Released
Status in “linux” source package in Karmic:
  Fix Released

Bug description:
  Upstream defaulted to HZ=100 to improve efficiency where highres
  timers are available; see benchmark at http://lwn.net/Articles/331607/
  .

  To remain competitive, Ubuntu Karmic should consider where this is
  possible. At present, i386 and lpia often don't provide a HPET or such
  adequate timer, thus leave HZ=250 on these arches. The opportunity
  thus exists on other architectures.

  Further discussion at:
  http://groups.google.com/group/linux.kernel/browse_thread/thread/e6b370e71ddfe153/f164d6068360b034?#f164d6068360b034

  Justification: keep Ubuntu Karmic competitive with other distros, and
  maximise user experience due to more efficiency
