I didn't, but I've compiled a new kernel with it in. Unfortunately, it doesn't seem to do anything useful :-(.
cat /dev/input/eventX | hexdump
returns nothing, not even for keyboard events, which makes me think I've gone wrong somewhere :-/

Sorry, I was wrong, I think I pressed a mouse button whilst connecting it and mis-read the info. The init is exactly the same.
However, the data sent from each one seems to be very different, (I've re-formatted this a bit to save space, but it's from the dmesg output):
mouse
Left button - 09 00 00 08 00 00
Right button - 0a 00 00 08 00 00
trackball
Left button - 01 00 00 00 00 00
Right button - 02 00 00 00 00 00

Good idea :-)
