I haven't yet attempted to track down whether it was this specific commit,
but sometime in the last few days, my notebook mousepad began behaving
very strangely.  I'm seeing a few different symptoms:

- The touchpad is much more sensitive than it was before, making it
  difficult to point it accurately at window borders, etc.

- When I hold down the mouse buttons to drag, that appears not to register
  properly, so I can't resize windows easily.

- Sometimes, the mouse cursor appears to stall and not move.  It then
  rights itself, but I'm not sure why.

psm now reports as "model Synaptics Touchpad, device ID 0" which I don't
recall it doing previously.
