Well, I managed to figure it out today.  Sending the special code to the 
MouseMan Dual Optical turns it into 800cpi mode.. much better!  Anyhow, I 
just put a test for this particular mouse in the hid_probe() and wrote the 
codes to the mouse.  Not sure if that's the best place.

This is for 2.2.20:
