Bug#523849: EmulateWheelButton option in xorg.conf no longer works

[Paul Ozog <pjozog@gmail.com>]

Subject: EmulateWheelButton option in xorg.conf no longer works
Package: xserver-xorg
Version: 1:7.4+1
Severity: normal

*** Please type your report below this line ***

After dist-upgrading to 7.4 from 7.3 EmulateWheelButton is not working correctly.  
EmulateWheelButton is set in xorg.conf as follows:

    Identifier     "Mouse0"
    Driver         "mouse"
    Option         "Protocol" "auto"
    Option         "Device" "/dev/input/by-id/usb-Logitech_USB_Trackball-mouse"
    Option         "Emulate3Buttons" "yes"
    Option         "Buttons" "9"
    Option         "YAxisMapping" "4 5"
    Option         "XAxisMapping" "6 7"
    Option         "EmulateWheel" "1"
    Option         "EmulateWheelButton" "8"


Xorg.0.log reports that every input device uses an EmulateWheelButton, even though it only is set above for the Trackball, and for the wrong button
(**) Microsoft Comfort Curve Keyboard 2000: EmulateWheelButton: 4, EmulateWheelInertia: 10, EmulateWheelTimeout: 200
(**) Logitech USB-PS/2 Optical Mouse: EmulateWheelButton: 4, EmulateWheelInertia: 10, EmulateWheelTimeout: 200
(**) Logitech USB Trackball: EmulateWheelButton: 4, EmulateWheelInertia: 10, EmulateWheelTimeout: 200

(Before, the xorg log correctly reported the EmulateWheelButton as 8, and _only_ for Mouse0)
Thanks.
