That is really strange. As it happens, the code currently there for high 
buttons is to handle an external ALPS Glidepoint touchpad I have with 3 
buttons that gives button events on buttons 1,2, and 4. The rest of my 
hardware behaves correctly, and the ALPS device reports itself as a 
mouse, not a trackpad, so I think the patch is fine. Crazy Apple hardware...
