dual dvi is still a bit of a work in progress as I don't have
functional hardware to test it at the moment.  I should have some soon
however and I'm working proper init of external tmds chips right now.
Also, FWIW, there was a bug in the bios connector tabling parsing that
led to a faulty tmds type for the external tmds connector.  you might
have more luck with 6.7.193.
