Patch: add support for a specific Xbox dancepad

I had to apply this patch to have my Xbox dancepad recognized as a
joystick and work with pydance.

The dancepad is the DDR Deluxe Dance Mat V.3.1 from Level Six. The model
number is X-BOX638. There's some information about the pad at
http://www.levelsix.com/product_info.php?cPath=21&products_id=31.

The patch applies on top of the kernel-2.6 files from the Xbox-Linux
CVS. It works under 2.4 also.

Notice that the value for the field isMat is 0, even though the device
is a mat. This is because the pad acts as a controller, sending button
presses both as digital buttons and analog axes. In any case, I found
that it was necessary in order to make the pad show up as a mouse and a
joystick.
