ctrl+alt+backspace stopped working with xorg-server 1.6.1.901

[Audio Phile]

Hello,

I'm using Arch Linux and my xorg-server recently got upgraded to 1.6.1.901.  At the same time, the ctrl+alt+backspace to restart gdm stopped working.  I am aware that I need to have added the "DontZap" "false" option in my /etc/X11/xorg.conf to enable this key combo some times ago, but even with this modification in /etc/X11/xorg.conf, the ctrl+alt+backspace does nothing ever since the upgrade.  I posted my /etc/X11/xorg.conf below if it helps trouble shoot.

Advice is appreachiated.
