Public bug reported:

Binary package hint: kubuntu-default-settings

Kopete has a settings for smooth scrolling in the contact list which is enabled 
by default.
This gimmick is implemented in such a bad way that kopete causes
almost 60 wakeups per second even if neither the contact list nor any chat 
window of kopete is open.

powertop:
Top causes for wakeups:
  16.9% ( 60.0)       <interrupt> : [EMAIL PROTECTED]:0000:01:00.0
  15.9% ( 56.6)            kopete : schedule_timeout (process_timeout)

The fix is to add
SmoothScrolling=false
to the [ContactList] section in
/usr/share/kubuntu-default-settings/kde-profile/default/share/config/kopeterc

After this change kopete causes only 1 wakeup per second:
   0.4% (  1.0)            kopete : schedule_timeout (process_timeout)
