I'm running a laptop that uses an Elantech touch pad over i2c.  I think I
get Elantech is quite close to cyapa, would this patch be a good place to
start for trying to get the touchpad to work?  There is also an Elantech
patch happening for the next release but that is not over i2c.  I'm
interested in making the change I just have little idea of this layer of
the machinery.

Thanks,
