I've been fighting with disabling touchpad and making middle button scrolling work on my Dell Latitude E4300 for a couple of days now. One problem for me was the fact that sometimes the kernel mouse driver lost sync:

psmouse.c: DualPoint TouchPad at isa0060/serio1/input0 lost sync at byte 1

This caused the pointer devices to dissappear and reappear with different names, e.g. "PS/2 Generic Mouse", "DualPoint Stick", "AlpsPS/2 ALPS DualPoint TouchPad", "PS/2 ALPS DualPoint TouchPad" and the mouse pointer occasionally jumping around when I accidentally touched the touchpad while typing. The sync problem got apparently cured for me with this: http://lkml.org/lkml/2008/12/8/182

A reliable way to cause sync errors for me is to keep moving the pointer with the pointing stick and simultaneously keep tapping the touchpad.

I'm running 64 bit Intrepid.
