[Intrepid] mouse properties regression : no touchpad tab

[®om]

In hardy, there was a third tab "touchpad" where it was possible to disable touchpad :

Some people seems to have this tab in intrepid, but I haven't (while I had it in hardy).

My xorg.conf :

Section "Monitor"
 Identifier "Configured Monitor"
EndSection

Section "Screen"
 Identifier "Default Screen"
 Monitor "Configured Monitor"
 Device "Configured Video Device"
 DefaultDepth 24
EndSection

Section "Module"
 Load "glx"
 Disable "dri2"
EndSection

Section "Device"
 Identifier "Configured Video Device"
 Driver "nvidia"
 Option "NoLogo" "True"
EndSection

I don't think it's a gnome-control-center problem, I added this to xorg.conf :

Section "InputDevice"
 Identifier "Synaptics Touchpad"
 Driver "synaptics"
 Option "SendCoreEvents" "true"
 Option "Device" "/dev/psaux"
 Option "Protocol" "auto-dev"
 Option "HorizScrollDelta" "0"
 Option "MaxTapTime" "0"
 Option "SHMConfig" "true"
EndSection

and synclient can't configure it

$ synclient touchpadOff=1
Can't access shared memory area. SHMConfig disabled?

A kernel problem?
