i wouldn't be suprised since that's a brand new board, very nice how do you like it so far? what're the rest of your specs?
back on topic: isn't there more than one SATA controller chip on that board (like a Sil or Promise)? check to see if it's the same controller as another mobo that does work and run it off those SATA ports.
edit: or purchase from a place with a liberal return/exchange policy and see just test it first to see if it works.
