Hi Roger, Is there anything new about this bug? Did you try 6.7.19x currently in experimental? What kind of machine is this? Your bug report makes me think of http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=443570 and https://bugs.freedesktop.org/show_bug.cgi?id=12525 This one is fixed upstream with Option "MacModel" "mini", it would be nice to test this with latest upstream git snapshot.
