I wonder if there's variations in the SD controller or something? I just asked Matthew Garrett to check his X220, and his has the same e823 controller as you, is running a 3.1-rc kernel, and everything's working. So it's not even variation in the controller model, it's something even more subtle. Perhaps try some different cards? What capacity/speed is the one you're trying? If there is a per-card difference, I suppose we'd expect it to be that slower cards work and faster cards fail (given the nature of the patch I linked in my last mail).
