Currently joydev will claim any device reporting ABS_X events. This
includes Synaptics touchpad in absolute mode, PC110 touchpad and both
touchscreens. Nothing bad happens except for strange input/jsX device
but it's still not right.
I think we need stricter rules for joydev matching, like in the patch
below. Unfortunately I do not own any joysticks, but I did go through
all code in input/joystick and I think I covered all possible cases.
