Well... I got the boards in. The good news is I got the boards and all the parts. The bad news is, the switching circuit doesn't work. I'm not sure what the issue is. I actually traced out the whole circuit and replaced the switching IC in case one was bad, but no joy.

I just populated this part of the circuit and fed 5VDC directly into it. The output just follows the input voltage minus about .3 volts, and the switcher just sits there mute. Obviously, the switching circuit isn't running. That kinda' puts a crimp in this one until I figure that out.
