Dell Vostro 1700 Touchpad (Scroll zones)

I am running Gentoo Linux, and trying to set up my laptop's touchpad so that the scrolling zones (horizonal and vertical) are recognised. I followed the advice on the Internet about using the synaptics driver. However, there is a problem - X.org does not recognise touchpad as a synaptics device:

Code:

(II) Synaptics touchpad driver version 0.14.6 (1406)
Touchpad no synaptics event device found (checked 18 nodes)
(**) Option "Device" "/dev/input/mouse0"
(**) Option "SHMConfig" "on"
(**) Option "LeftEdge" "80"
(**) Option "RightEdge" "940"
(**) Option "TopEdge" "130"
(**) Option "BottomEdge" "700"
(**) Option "VertScrollDelta" "100"
(**) Option "VertEdgeScroll" "true"
(**) Option "RTCornerButton" "3"
Query no Synaptics: 6003C8
(EE) Touchpad no synaptics touchpad detected and no repeater device
(EE) Touchpad Unable to query/initialize Synaptics hardware.
(EE) PreInit failed for input device "Touchpad"
(II) UnloadModule: "synaptics"

Furthermore, the touchpad is recognised by the kernel as a "Generic PS/2 Mouse" rather than an "alps" or "synaptics" touchpad:

Code:

cat /proc/bus/input/devices
...
I: Bus=0011 Vendor=0002 Product=0001 Version=0000
N: Name="PS/2 Generic Mouse"
P: Phys=isa0060/serio1/input0
S: Sysfs=/class/input/input6
U: Uniq=
H: Handlers=mouse0 event6 
B: EV=7
B: KEY=70000 0 0 0 0
B: REL=3

Any ideas on how I can deal with this?

Thanks

 

Take a look here.

 

I already have - it didn't work.
The problem was in the kernel psmouse driver - it did not recognise the touchpad as the alps device. The solution was found here: https://bugs.launchpad.net/ubuntu/+bug/129477
