Bug#539410: xserver-xorg-input-evdev: lost support for mousewheel scroll under kvm with option "-usb -usbdevice tablet"

["Michael S. Gilbert" <michael.s.gilbert@gmail.com>]

package: xserver-xorg-input-evdev
version: 1:2.2.3-1
severity: important

hello, i recently upgraded unstable on one of my kvm instances and
subsequently lost support for mousewheel scroll.
xserver-xorg-input-evdev was among the packages upgraded, and is my
best guess for the problematic package (other packages that were
upgraded that could be the culprit are libdbus-glib-1-2, makedev, and
linux-image-2.6.30).

note that this only occurs under kvm when the "-usb -usbdevice tablet"
option, which enables mouse over mode versus the standard mouse capture,
is used. when testing under mouse capture mode, mousewheel scroll works
just fine.

thanks for looking into this,
mike
