So... does anybody have a clue what this component is for? It looks like it might be some kind of resistor for the top pad on the left?

I noticed that the one on my board is missing (solder is there, component isn't) - may have never been there, I may have broken it off trying to squeeze the chip into my chassis.

Everything seems to work correctly, but I could probably replace it if I knew what it was.
