Hallo Heiko,

when I had a similar problem on my home PC I finally realized after 
hours of searching and hair pulling that during the update from debian 
stable -> testing the update process hadn't installed the newly 
introduced xlibmesa-dri package that includs all the dri specific 
drivers. As in your case everything seemed fine according to the logs 
but no 3D acceleration happend. The problem became finally visible when 
one started glxinfo with the following additional environment variable 
to show additional information (in my opinion a clear user interface bug):

LIBGL_DEBUG=verbose glxinfo

If that doesn't show any problems that you can solve yourself, maybe you 
could post the output of that command here.

Best regards,
Stephan
