2.6.0-test1: Synaptics driver makes touchpad unusable

[Ricardo Galli <gallir@uib.es>]

The new synaptics driver doesn't work with Dell Latitude Touchpad, it doesn't 
work any /dev/input/event?|mouse? and /dev/psaux neither (altough the same 
configuration worked at least until 2.5.70).

I tried with gpm and the X's synaptics driver from 
http://w1.894.telia.com/~u89404340/touchpad/index.html (as indicated in the 
kernel documentation) and none worked, although "cat < /dev/input/event0" 
showed garbage every time I touched the touchpad (no pun intended) iff evdev 
was loaded.
