My concern is, still, how would you identify this device. Will you extend also some ioctls to expose caps and extcaps? Otherwise it's difficult to identify this device automatically from the user-space. The user-space can know that it's button-less, yes. But, how can it know whether the device should be emulated via ClickZone? We can use a driver option to x11 synaptics driver for that, as I already sent you another patch. However, the driver option is nowadays not preferred because xorg.conf is being dead on new systems... Or maybe HAL (or whatever upcoming one) can check the vendor/product id of the machine (not the device) to provide the information. OTOH this will also need frequent updates.
