Description:
When I set X.org to use "evdev" as driver and "evdev" as XKbModel, my system gets very unstable.

Additional info:
* current, extra and community packages
* config:

Section "InputDevice"
# generated from default
Identifier "Keyboard0"
Driver "evdev"
Option "Protocol" "evdev"
Option "Device" "/dev/input/event11"
Option "XkbModel" "evdev"
Option "XkbLayout" "us"
Option "XkbOptions" "compose:lwin"
EndSection

(I know that the "Device" option is discouraged, but my keyboard has two /dev/input/event1* files -> see http://gentoo-wiki.com/HOWTO_Microsoft_Natural_Ergonomic_Keyboard_4000)

Steps to reproduce:
Configure the Keyboard to use "evdev" as driver and "evdev" as XkbModel. My gVim constantly crashes when I start it, and enter "ESC" or "j" (not in input mode!).

Additional note:
I wrote a udev rule to fix the keyboard to a certain /dev/input/event file (see the linked how-to):
KERNEL=="event*",SYSFS{modalias}=="usb:v045Ep00DBd0173dc00dsc00dp00ic03isc01ip01", MODE="0644", NAME="input/event11"
KERNEL=="event*",SYSFS{modalias}=="usb:v045Ep00DBd0173dc00dsc00dp00ic03isc00ip00", MODE="0644", NAME="input/event12"

The whole configuration works on Ubuntu Feisty (32 bit version).

My current solution is not to use "evdev" (which would enable only two more special keys - the "Zoom" slider).
