Do what obrentharris (and no doubt others) said: loosen the bolt a few threads, put a piece of wood on top of the bolt, and whack it with a hammer to dislodge the wedge.
I guess I should have qualified this a bit more, my sense was the OP had already broken the wedge bolt loose because the stem was moving...So, yes, all are correct about the "soft " blow to the bolt, which I have used to break a wedge bolt loose when a stem is stuck etc.
If in fact the wedge was "already" loose (moving side to side) at the stem.....the way to confirm this would be "seeing" it at the bottom of the fork which is easier when removing the wheel and brake or "hearing" around bouncing in the tube.
If the bolt is in fact already loose and this can be "confirmed", then something else is causing the problem.
