Heh.  I've actually got it wired up to the i2c bus on a BeagleBoard from TI.

I've got a new version of the driver which I'll post when I get back
home and have a chance to properly test it.  I've implemented Nunchuck
and Classic Controller support so I could play with implementing
multiple protocols in a clean way (even though I don't actually have a
classic controller yet).  Motion Plus should be straight forward to
add, but I'll probably leave that as an exercise for somebody else.
