** Description changed:

- When the synaptics driver is called, it looks for the first touchpad
- that isn't already handled by synaptics. This is wrong in so many ways,
- especially when, for example, it grabs the magic trackpad that's driven
- by evdev when it was really looking for the normal trackpad on the
- laptop.
- 
- Synaptics must be stopped!
+ Two touchpad devices A and B
+ X enumerates A before B
+ They both have a /dev/input/event* node and a /dev/input/mouse* node
+ I set up xorg.conf to use evdev for A
+ A gets handled by evdev
+ B's /dev/input/mouse* node gets probed by synaptics
+ it doesn't match /dev/input/event* in the synaptics probe function, so synaptics runs the eventcomm AutoDevProbe callback
+ the AutoDevProbe callback finds the first evdev node that isn't grabbed by synaptics already
+ in this case, it finds A and grabs it
