If there's still some interest in a few days I will figure out how much dummy plugs and resistors cost me and ship a few (worldwide).

I would just like to confirm that shorting the DVI connector on the card itself can destroy the card. Because it happened to me. Sapphire 5770, used a single 68Ohm resistor, card showed up in Catalyst and poclbm, seemed to be working fine ... and then I had to reboot for an unrelated reason. Win 7 would hard lock within 60 seconds of login. Even the reset button didn't work (which I didn't even think was possible). Pulled the card, works fine. Just got a replacement after ~2 weeks. How much money did that cost me, losing ~178MH/s for 2 weeks? So it's not worth it, boys.

I used this 5 Second Dummy Plug guide. It seemed like sound reasoning, but don't bet on it.

This is what I'm using now on 2 other cards - no problems whatsoever.

PM if interested in dummy plugs, I think I have 2 or 3 extras. 75 Ohm is the "ideal" resistor, apparently, but my local Radio Shack only stocks 68s and they seem to work fine. It's not hard to make them and 5 resistors cost a buck.
