Well, joydev consider our Pad devices as joysticks and associate a
/dev/input/jsX node for them.
The problem is that it consider the ABS_X value as 0, and sends some
spurious joystick events saying the X axis is full left (Y too, but full
up). Given that we are basically screwed, add one more BTN which tells
joydev to ignore the Pad device and doesn't interfere with the rest of
the udev rules and the processing.
