I have an iBook G4. The trackpad used to work in earlier versions of Ubuntu, but I just finished upgrading and it no longer works in Ubuntu 11.10.
alex@orientalibombus:~$ sudo trackpad show
no trackpad !
I checked /var/log/Xorg.0.log and searched for ADB mouse and this seemed to be the relevant part:

There are sections regarding my Logitech mouse, the ADB keyboard, powerbutton, etc. Can you spot anything suspicious?
