You can add SkyAuction to that list, although the company equivocates in its response to an FAQ on FF miles on tickets bought through their bidding process. SkyAuction says "It depends on the auction. The best way to find out is to send an email to us before you bid. Please fill out our Ask a Question form. We will provide you with the most up-to-date information available to us at that time. Please remember that as airline policies are always subject to change, it is the airline that has the final say at the time of travel."

I was the successful bidder on 2 tix on UA LAX -> BKK in 2002, but I couldn't get any FF miles.
