Xorg.0.log diff between the working and broken xorg-x11-drv-evdev

Description of problem:
Updated xorg-x11-drv-evdev broke mouse movement in a Xen F11 guest. I access the guest's console using virt-manager. The mouse pointer does not move, although clicking works.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Start the F11 guest using virt-manager.
2. When gdm screen appears, try to move the mouse.
Actual results:
The mouse pointer stays centered on the guest screen.

Expected results:
The mouse pointer should move.

Additional info:
Downgrading to xorg-x11-drv-evdev-2.2.1-3.fc11 fixes the bug.

Rawhide has the same problem.

I need to see how the Xen virtual pointer device looks like.

Please download http://people.freedesktop.org/~whot/evtest.c, compile it
with gcc -o evtest evtest.c and then run it as root against the devile file.
The device file is /dev/input/eventX, where X is a number. You can get the
right device file by looking into /proc/bus/input/devices.

You need to run this command in the guest.

Is there some other information I could provide?

Bug 523914 describes the same issue, it's present in F11 and rawhide and has the same cause.
