Well, you are the first one I hear of having issues with an X2 card on the DFI. I was one of the first people to get a retail mobo, and I had my X2 already running in the previous DFI x38, and I have tried almost all bios versions between the oldest and latest, so it should work. I am still guessing it's the card's bios. I got a PowerCOlor reference design card (Heatkiller too ) so maybe I can extract my card's bios and send it to you, if flashing your mobo bios doesn't help.

Have you ruled out the PSU? No red lights may be lighted on the back of the cards when you turn it on, otherwise it's a power issue.
