Well if I get a chance I might try to do it for the scx200 at some point
(since I do use it) although given the current i2c driver works just
fine and I have no need for the rest of the gpio lines what so ever
there isn't that much insentive to do so yet.

Removing the existing i2c driver would seem like a mistake at this time
though.
