Just reviving this thread for a bit. There's a frame & components (both wheels are already gone) locked up at my local grocery store and the manager is willing to let me have the remainder of the bike (assuming no one claims it and it's been sitting there for over a week now already). However neither he nor I have actually attempted to break through the Kryptonite KryptoLok STD U-lock yet. Any suggestions on how to best accomplish this? The lock is secured through the top horizontal bar of the rack and through the frame (right now it's sitting next to the headtube).

I'm not sure my car's screw jack will fit in there. Will bolt cutters work? I have a hacksaw but no power tools.
