I'd be more happy if it was just an input device. If non-wired interrupt is a common case then we should probably add polled input device mode, but we certainly should not register completely non-functional input device as the driver does now. We also have a way of retrieving current (or rather most recent) coordinates via EVIOCGABS so I am not sure why we want the sysfs way of retrieving coordinates as well. Regarding power mode - I really believe that this should be done on the driver core level instead of implementing "manual off" in every single driver out there.
