Comment 346 for bug 606238

First of all: thanks for the work guys

I am on Dell Latitude XT
Alps hardware: touchpad, 4 buttons, 1 stick
Touchpad is detected as PS2 mouse, synapticts not loaded.
Touchpad works (tapping/moving), but not very sensitive cq. delays, buttons an stick work
The insensitivity / delays made me look for changing the setup.
And that made me aware of the synaptics issue.
(I never use scrolling so had not noticed anything missing ...).
Installed Os's:
wheezy 3.2.0-4-amd64 / xubuntu 3.2.0-40-generic / XP .
Downloaded psmouse-alps-1.3 from http://dahetral.com/public-download.
Unfortunately, there is no support for Dell Latitude XT.
Found an old mail exchange (2009) from Dmitry Torokhov.
This gave me a clue as what to try.

Added the following line to alps_model_data[]
       { { 0x73, 0x00, 0x14 }, 0x00, ALPS_PROTO_V2, 0xf8, 0xf8, ALPS_DUALPOINT | ALPS_FW_BK_2 }, /* Dell Latitude XT */

resulting dmesg:
psmouse serio1: alps: E6 report: 00 00 64
psmouse serio1: alps: E7 report: 73 00 14
psmouse serio1: alps: EC report: 10 00 64

input: DualPoint Stick as /devices/platform/i8042/serio1/input/input10
input: AlpsPS/2 ALPS DualPoint TouchPad as /devices/platform/i8042/serio1/input/input11

Touchpad recognized, tapping works, scrolling works, buttons work.
The stick however goes haywire, sending random click events when touched.
This is in both xubuntu and wheezy
In wheezy I had to enable tapping, in xubuntu tapping worked 'out of the box'

My questions:
What is the status of Latitude XT support in alps.c ?
Can I help ?
Where to put these questions ?

I am pretty comfortable with linux and C
I also have win XP with latest Dell Alps driver on this laptop
(must say, I am not a happy windows hacker but can do ...)
