You can add fusion-icon to the autostarted applications.
I personally prefer not to, because in my case, I'm always tinkering with the system, so I may break X from time to time, in which case, the compiz thing could get really annoying.
But if you dont do anything like that, you can add the fusion-icon command to the autostart.
FYI. Fusion-icon is probabbly the best way to start your compiz session. Not only does it load everything you need, but it provides you with the tray icon so you can access the configuration easily.
