That is PRECISELY the correct way to go about it. Take the tax loss for 2011 and then IF, by some bizarre stroke of good fortune, anything ever comes back, then you treat it as a new holding with a zero cost basis. And, yes, you CAN still take the tax loss now and still have the position if it's ever reincarnated.
So why'd you give me so much grief over telling people about the Form 1040-X up to now?
