Indeed, just removing the input driver key is enough. The line about the 
capabilities was a left-over from trying to have the joystick NOT recognized 
as a mouse in the first place.

A previous version read something like:

        <remove key="info.capabilities"/>
        <merge key="info.capabilities" type="strlist">input.joystick</merge>
        <merge key="input.x11_driver" type="string">joystick</merge>

If memory serves correctly without the capabilities lines the joystick 
driver would not work correctly, as it was getting confused by the buttons. 
But this was some time ago and I haven't played with the settings recently.

Cheeers,

Magnus
