Xorg fails w/scfb: Cannot run in framebuffer mode. Please specify busIDs

OK. These suggestions may just be shots in the dark; but...
You might give Xorg -configure a try, to see if it might
provide you with some hints as to what it *thinks* you have.

I notice in your Xorg.0.log that X barfs on AIGLX.
You might just try adding the following to the
Section "ServerLayout" block:

Option         "AIGLX" "false"

and see if that overcomes the problem.


Hope this helps, and apologies for top posting.
