This were the results with a ADD2-N card. I finally managed to buy an
ADD2-R card (which are designed for BTX boards AFAIK) on ebay with
exactly the same problem. No matter if I plug in the ADD2-N or ADD2-R
card or use the onboard connector it's always detected as TMDS-1. So
the answer to the next question is yes. :-(

So there is only one hope for 2x DVI with Intel - to find a Wintec 2x
DVI on ebay (the previously available cards are currently redesigned).
