Now that Linux 3.9 is making its way into circulation, let's summarize
the reported issues to date:

1) No Dolphin V2 support.  Still need to borrow hardware to fully
understand the report format and make edge scrolling work without
excessive pressure.  I believe we have a good init sequence.

2) Resync errors:

[1766509.702598] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 
lost sync at byte 6
[1766509.712794] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 - 
driver resynced.
[1766509.722987] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 
lost sync at byte 6
[1766509.733151] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 - 
driver resynced.
[1766509.743293] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 
lost sync at byte 6
[1766509.753533] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 - 
driver resynced.

I see these pop up in dmesg every week or two; they run for maybe a
minute or so and then vanish, with no obvious ill effects.  Not sure how
to reproduce them.

3) Click-and-drag (e.g. selecting text in an xterm) suddenly quits
working.  I've only seen this happen once.  Unloading and reloading
psmouse.ko fixed it.  This problem mystifies me because when I ran xev,
I still saw all of the proper events coming from the input device.  So
maybe it was caused by something higher in the stack.

4) Tap-to-click is broken on Rushmore[1].  Root cause: when
transitioning from Linux 3.8 (touchpad detected as generic PS/2 mouse)
to 3.9 (touchpad detected as an ALPS touchpad), tap-to-click in the
pointer settings may need to be enabled by hand.  If the touchpad is
detected as a generic PS/2 mouse, tap-to-click will work regardless of
this setting.

5) Pointer jumps all over the screen after suspend/resume on a Rushmore
touchpad.  Seen once, cannot reproduce.

6) "Noisy" X/Y values on Rushmore[2].  Reporter is investigating whether
this shows up on other drivers.  Three possibilities include: i) it's
noisy everywhere, even in Windows; ii) the input data is noisy, and the
driver needs to clean it up; or iii) the other drivers get "clean"
report data but we're using a bad init sequence so our report data is
sketchy.


Any hints on reproducing #2, #3, or #5 would be appreciated.
