Sorry for the noise, this is not related to that bug at all.
Some yahooing lead me to xorg.conf
SubSection  "extmod"
   Option    "omit xfree86-dga"   # don't initialise the DGA extension
This solved my problem. I have no idea what DGA or extmod really is, 
even less why it again is a xinerama dependend issue.

Is there a good overview of the xorg components? Like what is RANDR and 
AIGLX and WFB and RandRRotation and so on.
