I found the same this morning. Grr.

$ less /var/log/Xorg.0.log
...
(II) Cannot locate a core pointer device.
(II) Cannot locate a core keyboard device.
(II) The server relies on HAL to provide the list of input devices.
         If no devices become available, reconfigure HAL or disable 
AllowEmptyInput.
...

So, I added

Section "ServerFlags"
         ...
         Option      "AllowEmptyInput" "off"
EndSection

to xorg.conf, restarted the X server and that did the trick.

Not fun, but fortunately not too hard to route around.
