[OM] Magical cures for stuck rewind lever?

[NSURIT]

I have an OM 2S that won't allow me to advance the film or release the 
shutter.  The rewind button you depress to rewind your film appears to be 
stuck in the down position, which I'm sure is part of the problem.  Short of 
sending this body to the bone yard or in for a CLA, does anyone have any 
ideas that might allow me to cock the shutter/release the rewind button.  BB
