 > There is a way to put the ALPS touchpad in a deep-sleep state that saves
 a little power.  I hesitate to do that because you would need a
 significantly more complex wakeup sequence afterwards.  I'm pretty sure we
 don't have the resources to do all the testing that would require.  Also,
 the new Synaptics-based keyboard subsystem is rather different in that
 regard, so all the work would need to be done twice.

 Dilinger has told me that he does this in the ALPS driver as one of the
 "fixes" when it detects that things are jumpy. Only he calls it power
 cycling.  I expressed the same concern as Mitch. ie "How did you wake it
 back up?"  Dilinger claims that if you just start sending commands to the
 device that it will wake back up.  The docs I remember looking at said
 something about holding the clock low for close to 1 second or some such.
 I've not verified Dilingers claims but he was very confident that he was
 indeed putting it to sleep and waking it back up without EC support.
