I have managed this with the latest everything.
Initially I had two blank screens.
In xorg.conf, intel device section,
I had to set the ForceSDVODetect option to see TMDS-2
I had to comment out Monitor-LVDS option, even though it was a null
monitor, to see TMDS-1.
I had Monitor-TMDS-1 and Monitor-TMDS-2 set.
I did find, (and commented in another posting), that the intel driver
incorrectly uses a reserved bit to determine if the TMDS-2 monitor was
initially connected.
