Hi!  This is my first post (of hopefully many useful ones in the
future!) to the maemo-developers list.

I definitely remember some documentation on this.  I can't seem to
find it on the wiki so perhaps it was at the Maemo Summit.  Anyway the
procedure is basically:

1) Run 'powertop' in xterm (or via ssh) and observe a rough number of
wakups per second
2) Run the application, then switch back to ssh/xterm
3) Run powertop again.  Observe the number of wakeups per second to
see if its much larger than before.

I have already used this procedure succesfully to find a widget which
was causing a huge number of wakeups in hildon home
