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

[Audio Phile]

FINALLY!  It's fixed.  See the xorg page on the Arch wiki for details.

Basically, the solution came from adding the following line to /usr/share/hal/fdi/policy/10osvendor/10-keymap.fdi

<merge key="input.xkb.options" type="string">terminate:ctrl_alt_bksp</merge>

After a restart of hal, it worked.

Thanks to all who replied!
