Thanks for the reply. I have tried running Xorg -configure a few times w/o
success. Indeed, I used it to create the xorg.conf file that I'm trying to use
currently with changes to the Device section ("scfb" vs "intel") and the
addtion of the BusID setting.
Also, turning off AIGLX did disable it but made no change to the segmentation
fault (identical stack trace).
