Comment:

 Note: the "background" bug to this, explaining why it Synaptics mode has
 been disabled, is #8901 .

 FWIW, I have built a psmouse.ko with synaptics. Testing on 10.1.2 and CL1C
 hardware...

  * Installed psmouse.ko
  * rmmod / modprobe, seen as SynPS/2
  * Configured x.org to use synaptics based on #8942 -- note that no
 scrolling settings are requested. Restarted X.org
  * Touchpad works correctly, no jumpiness observed
  * Tried the various tests outlined in #8901 -- could see no problems.
 Fast typing was accurate and without lags, even with some fingers hovering
 over TP.
  * Vertical scrolling on the right-hand-side of the TP works. Tested in
 TurtleArt and Terminal. No horizontal scrolling (probably not on by
 default).
  * S/R -- if we are resuming on TP activity the "first stroke" is missed.
 This is a regression. With 'our' driver the first stroke is usually
 registered (but acts more like a jump).
  * The xorg synaptics driver grabs the raw device and ignores olpc-kbdshim
 -- which does not understand the synaptics protocol anyway.
  * Seems passing proto=bare reverts the synaptic-enabled driver to the old
 behaviour.
