Thinkpad 3rd Mouse button gone after Hardy upgrade.

[linuxd00]

Hi,
after the upgrade my third mouse button is gone on my Thinkpad X31(Hardy + compiz running perfectly else)...

Xorg.conf in gutsy (3rd button worked)used to look like this:

Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/input/mice"
Option "Protocol" "ExplorerPS/2"
Option "ZAxisMapping" "4 5"
Option "Emulate3Buttons" "true"
Option "Buttons" "7"
Option "ButtonMapping" "1 2 3 6 7"
Option "MinSpeed" "0.45"
Option "MaxSpeed" "0.75"
Option "AccelFactor" "0.020"

EndSection

after the upgrade only button 1 & 2 work. I reconfigured xorg and now it loos like this(but the still only trackpad buttons 1 & 2 work):

Any hints? or helps?

Solved.
Put this in the mouse section:

Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/input/mice"
Option "Protocol" "ImPS/2"
Option "ZAxisMapping" "4 5"
