with the quirk, the device exposes three /dev/input/event files, the 
highest of which sends the actual events now (in X/Y). number two looks 
like a mouse device (like yours), number three like a touchscreen 
(BTN_TOUCH, etc.)
without the quirk, I only get two devices, the second of which looks 
like a mix of mouse/touchscreen and it sends ABS_Z/ABS_RX while ABS_X 
and ABS_Y are mute. I can get you the full evtest blurb but not before 
Monday, the screen is in the office.

where do I get nwtool from? google is unusually quiet about it.
is it possible that you changed the report mode (or have it different to 
me anyway) and that affects things?
