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.

$ dmesg

No, it didn't help. With the above patch, the x server gives the following errors:

Looks like the wrong protocol is specified in the X driver configuration. You must set "Device" to "/dev/input/eventX" and "Protocol" to "event", where X is probably 0 in your case.

I can replicate this problem with 2.6.0-test1 on a Dell Inspiron 4150 laptop as well.

This doesn't look like the same problem. There is no "reset failed" message. Are you using the correct XFree86 driver:

        http://w1.894.telia.com/~u89404340/touchpad/index.html

Also, note that the driver doesn't work with gpm yet.
