Put the following to your xorg.conf:

<snip>
Section "ServerFlags"
  Option "DontZap"         "off"
  Option "AllowEmptyInput" "off"
  Option "AutoAddDevices"  "off"
EndSection

Section "InputDevice"
  Option "XkbOptions" "terminate:ctrl_alt_bksp"
EndSection
</snip>

This works for me very reliable (xorg-7.4_2).
