Thank you very much. System does now boot with radeon driver and direct rendering on.
Thus I have a good workaround. I did not check which of the two options "PreferredMode" Virtual did make the job. When you would like to have any additional tests or information I would be pleased to help you.
Relevant xorg.conf part now looks like (i.e. no BusType odr DRI off option needed):
