The diff below adds support for ALPS touchpads to the pms(4) driver.
I'm looking for testers with or without ALPS hardware, especially if you
have a touchpad, to be sure it doesn't break anything.
Currently, ALPS DualPoint are untested and support for special buttons
(back, forward, etc) is missing because I don't have such hardware.
I use the following synaptics(4) configuration for edge scrolling and
simple left tapping:
xinput set-prop /dev/wsmouse0 Synaptics Finger 25 30 60
xinput set-int-prop /dev/wsmouse0 Synaptics Tap Action 8 0 0 2 3 1 0 0
xinput set-int-prop /dev/wsmouse0 Synaptics Click Action 8 1 0 0
xinput set-int-prop /dev/wsmouse0 Synaptics Edge Scrolling 8 1 0 0
Compared to the previous version, I left the Y-axis translation because
it's also needed for the COMPAT mode.
New version of the diff. Recent ALPS touchpads use a totally different
protocol and are not supported.

Using { 0x7326, ALPS_UNSUPPORTED } is not best idea.
Instead
if (alps-model ALPS_UNSUPPORTED)
use
if (alps-model == 0)
or even better
#define ALPS_UNSUPPORTED 0
...
if (alps-model == ALPS_UNSUPPORTED)
If the device is not in alps_quirks, then it will automatically be
ALPS_UNSUPPORTED. No need to register each device is not supported.
