Pour le touchpad, tout ca se règle avec le xorg.conf.
J'avais le même problème au début mais en remplacant la partie concernant le trackpad par celle qui suit, ca marche très bien. Par contre c'est un Ibook donc je sais pas du tout si ca marche sur un powerbook, essaie de l'adapter en fonction:
Section "InputDevice"
Identifier "Mouse"
Driver "mouse"
Option "SendCoreEvents" "true"
Option "Protocol" "ExplorerPS/2"
Option "Device" "/dev/input/mice"
Option "ZAxisMapping" "4 5"
EndSection
