Description of problem:
Latest rawhide updates killed compiz on an Intel GM965. Since many xorg-x11 bits
changed I cannot say whether this was the driver or some server component.

I resetted everything and tried to reenable desktop-effects:

$ gconftool-2 --recursive-unset /apps/beryl
$ gconftool-2 --recursive-unset /schemas/apps/beryl
$ gconftool-2 --recursive-unset /apps/compiz
$ gconftool-2 --recursive-unset /schemas/apps/compiz
$ gconftool-2 --unset /apps/gnome-compiz-preferences
$ desktop-effects
compiz (core) - Fatal: No GLXFBConfig for default depth, this isn't going to work.
compiz (core) - Error: Failed to manage screen: 0
compiz (core) - Fatal: No manageable screens found on display :0.0

Actual results:

Expected results:
working compiz

Additional info:
For a couple of days now I have been running w/o any xorg.conf due to testing
bug #441589. AIGLX and compiz were working.

Now neither a xonf.org free setup, nor my previous system-config-display created
xorg.conf make a difference. There is also not any clue in the Xorg.0.log why
this isn't working. Here is a diff to the previously "working" log:
