I have similar problem

There are 4 interesting symptom

1. i8042 interrupt trigged when touchpad move up/left/down/right
2. evst shows the coordination when touchpad move up/left/down/right
3. there is no event in XEV when touchpad move up/left/down/right

To get the property of touchpad, you can type
$ synclient -l
