Could easily be verified by: a) plugging a usb mouse in, those > don't get disabled and b) running evemu-record against the device with the > tablet mode switch bits (the WMI hotkeys device?) and checking the switch > state. If it's 1 when the device isn't in tablet mode, then we have the > culprit.
