O.K. - so first I try to rebuild base. I have already got 
WITH_NEW_XORG in my /etc/make.conf . Support for AMD/ATI can't be 
worse than it was with xorg-7.5 . For now I would be happy to get 
some kind of gui back - even with VESA driver.

Thanks for your help so far - I will report what happens.

Greetings

Peter.
