Default Bug#680154: ALPS Touchpad Recognized as "PS/2 Generic Mouse" under Debian Squeeze on Lenovo G360 Laptop(post again)

Package: linux
Version: 3.2.4-1~bpo60+1

System information:

Debian Squeeze, kernel in squeeze-backports: 3.2.0-0.bpo.1-amd64, and
also tested on kernel 3.4 compiled with "make oldconfig" based on
config-3.2.0-0.bpo.1-amd64, no lucky.

This bug has been reported as a xserver-xorg-input-synaptics package
bug at "http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=679750", but
they said "Not an X bug, the name shown is whatever the kernel
reports.", and reported at
"http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=679844", but seems I
posted the wrong package name(Package: linux-image-3.2.0-0.bpo.1-amd64;
Maintainer for linux-image-3.2.0-0.bpo.1-amd64 is (unknown), no reply
after 2 days. so I report it as akernel bug here.

My lenovo G360 has an ALPS touchpad, shows in Windows 7 Home Editition
OEM in this laptop. Under Debian Squeeze in the same laptop, the left
and right key, single and double tap, tracking of touchpad works
well. But, there isn't touchpad tab in gnome mouse setting dialog, so
I can't setup edge scrolling and disable touchpad on typing. xinput
shows it is a "PS/2 Generic Mouse". Below is the detail information.

"synclient -l" shows:

Couldn't find synaptics properties. No synaptics driver loaded?

"xinput --list" shows:

⎡ Virtual core pointer id=2 [master

"cat /proc/bus/input/devices" shows (only post the section of "PS/2
Generic Mouse"):

There is no touchpad or synaptics information in the
"/var/log/Xorg.0.log" I have tried too many methods found on internet,
such as:

1, add "psmouse.proto=imps(or exps)" into kernel parameters;

2, add file "etc/X11/xorg.d/10-synaptics.conf", the content as below:

Section "InputClass"
Identifier "touchpad catchall"
Driver "synaptics"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
Option "SHMConfig" "on"
Option "TapButton1" "1"
Option "TapButton2" "2"
Option "TapButton3" "3"
Option "VertTwoFingerScroll" "on"
Option "HorizTwoFingerScroll" "on"
EndSection

3, Tried patched psmouse.ko. I downloaded linux-source-3.2, and
applied patch found on
internet
(Resend-Add-support-for-Intellimouse-Mode-in-ALPS-touchpad-on-Dell-E2-series-Laptops.patch,
see attachment), I have not use cat *.patch | patch -p1, just copy the
modified code into linux-source-3.2 and recompile psmouse.ko. But no
lucky.
