Could ypou please load evbug module or run evtest utility and
verify that the driver produces reasonable events?

Mousedev (i.e. /dev/input/{mouseX|mice} will provide crude
emulation of normal mouse; there is evtouch X driver that
should work better. You may also try evdev X driver from
recent releases of x.org; as far as I know they want it to
supesede evtouch eventually.
There are also solutions based on tslib library that allows
touchscreen calibrating, etc. but I am not familiar with it
so I am CCing Richard Purdie.
