But I did take a debug dump from dmesg, which is attached. According to Chris the monitor doesn't respond to a periodic probe and is declared as disconnected. Currently running 3.4, happens on earlier kernels as well.

To test whether your system suffers from the same problems, please test with this quick debug patch which disables all HDMI outputs. Note that with this patch only DP monitors will work on external connectors.
