Disabling Touchpad in UltraNav-Keyboard

Question

Hello,
I'm using an IBM Thinkpad UltraNav-Keyboard (this one) and i'd like to disable the touchpad.
I've googled around, and all I've found is that I should make some changes to xorg.conf and/or the hal-policies.
I did so, but nothing happend. Even removing both, the xorg.conf and all the hal-policies didnt change anything.
Another option i've found is to change the behaviour using the Gsynaptics-Config-Tool.
I added  'Option "SHMConfig" "true"' in the section "InputDevice" in the xorg.conf and created an shmconfig.fdi with the following content:
<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
<device>
<match key="input.x11_driver" string="synaptics">
<merge key="input.x11_options.SHMConfig" type="string">True</merge>
</match>
</device>
</deviceinfo>
But when I try to run gsynaptics it still says:
GSynaptics couldn't initialize.
You have to set 'SHMConfig' 'true' in xorg.conf or XF86Config to use GSynaptics
And yes, I've restartet HAL and X, I even rebooted. Still no change.
lshal ouptut for input.device:
input.product = 'Macintosh mouse button emulation' (string)
input.product = 'Synaptics Inc. Composite TouchPad / TrackPoint' (string)
input.product = 'Synaptics Inc. Composite TouchPad / TrackPoint' (string)
input.product = 'Lite-On Tech IBM USB Travel Keyboard with UltraNav' (string)
input.product = 'Lite-On Tech IBM USB Travel Keyboard with UltraNav' (string)
cat /dev/input/mouse1 responds to movements on my touchpad,
cat /dev/input/mouse2 responds to the trackpoint.
So, what do I have to change to disable the touchpad?
Thanks in advance,

Ok, i read that but found nothing about governing and governed modules.
But I found out a couple of other things:
First of all I could  get the trackpoint scrolling using this fdi:
<?xml version="1.0" encoding="UTF-8"?> <!-- -*- SGML -*- -->
<deviceinfo version="0.2">
<device>
<match key="info.capabilities" contains="input">
<match key="info.product" contains="Synaptics Inc. Composite TouchPad / TrackPoint">
<merge key="input.x11_options.EmulateWheel" type="string">true</merge>
<merge key="input.x11_options.EmulateWheelButton" type="string">2</merge>
</match>
</match>
</device>
</deviceinfo>
I'm able to disable the touchpad using "xinput set-prop 8 121 0" , see xinput list- and xinput list props-output.
Notice the device "Synaptics Inc. Composite TouchPad / TrackPoint" is listed two times, i don't think that should be like that?
Using hal-device I found out that the pointing devices are driven by evdev.
When I created an hal-policy to load the Synaptics-Driver,  neither trackpoint nor touchpad worked.
Xorg.log provides information why:
(II) config/hal: Adding input device Synaptics Inc. Composite TouchPad / TrackPoint
(II) LoadModule: "synaptics"
(II) Loading /usr/lib/xorg/modules/input/synaptics_drv.so
(II) Module synaptics: vendor="X.Org Foundation"
    compiled for 1.7.3, module version = 1.2.1
    Module class: X.Org XInput Driver
    ABI class: X.Org XInput driver, version 7.0
(II) Synaptics touchpad driver version 1.2.1
(**) Option "Device" "/dev/input/event6"
(--) Synaptics Inc. Composite TouchPad / TrackPoint: no supported touchpad found
(EE) Synaptics Inc. Composite TouchPad / TrackPoint Unable to query/initialize Synaptics hardware.
(EE) PreInit failed for input device "Synaptics Inc. Composite TouchPad / TrackPoint"
(II) UnloadModule: "synaptics"
Apparently the xf86-input-synaptics-driver does not (or no longer?) support the Ultranav-Keyboard?
I wonder, because I read a lot about this the past few days, i'm almost sure i found some people who were using this keyboard with that driver.
Unfortunately i'm not able to find anything about that again.
Is there anything I could still try?
Otherwise i'll try this synaptics-usb-driver, that is reported to work.
