You have a good point there, and I forgot to mention that. That program kinda depends on beryl, and I'm not sure it the new compiz has the same features to start the program. But the dock did have, and was auto started when beryl was started.
So your correct you can start it manually. And if compiz does not auto start it, he could always add it into the auto start applications for kde.
Sorry guys I forgot about that.
