Bug#733238: Xserver ignores xorg.conf

["Christian Meyer" <c2h5oh@web.de>]

Hello there,
 
I got bitten by this bug, too. I have a "Logitech Marble Mouse Trackball" and it worked fine with squeeze and wheezy.
I created a xorg.conf and xorg seems to ignore it, especially the "EmulateWheelButton" which should be button 8 but is button 4:
 

$ cat /etc/X11/xorg.conf
Section "InputDevice"
    Identifier "Marble Mouse"
    Driver      "mouse"
    Option "Protocol"    "ExplorerPS/2"
    Option "Device"      "/dev/input/mice"
    Option "Buttons" "9"
#    Option "Emulate3Buttons" "true"
#    Option "Emulate3Timeout" "50"
    Option "ChordMiddle" "True"
    Option "EmulateWheel" "True"
    Option "EmulateWheelButton" "8"
    Option "XAxisMapping" "6 7"
    Option "YAxisMapping" "4 5"
EndSection

There is no xorg error message:

$ cat /var/log/Xorg.0.log | grep \(EE\)
    (WW) warning, (EE) error, (NI) not implemented, (??) unknown.
