Created attachment 136121 --> https://bugzilla.kernel.org/attachment.cgi?id=136121&action=edit Log of fglrx with DCE 2.0 and DCE 3.0 cards (HDMI setup)
Current code isn't based on a perfect RE method, we were mostly observing registers, not tracing fglrx operations. It should be a good idea to trace fglrx operations and improve radeon's code to match it as much as possible.
