No, thats not possible as the /dev/input/event6 is an uinput device and
not provided by any kernel driver. On the palmpre machine we have a
special situation with the touchscreen. The kernel gives you access on
the touchscreen through /dev/touchscreen. It can be opened only once. So
we have written a touchscreen management daemon called tsmd. It opens
/dev/touchscreen, creates a new uinput device, processes all touchscreen
events via tslib and reports them to the user via the uinput node. So
there is no /dev/input/touchscreen0 ever available.
