...then it's a configuration problem rather than not having the right module.
I'll see what I can come up with to get you back on track.
in the interim try:
Code:
sudo modprobe -r psmouse
followed by:
Code:
sudo modprobe psmouse proto=imps
This removes the module (driver) and then reinstates it with a modified parameter.
If this makes it move we can make the change permanent.
