Hello tarquin, I am Abe. I see you are having some crazy issues with your alien ware machine. My first step would be looking into a new logic board. the smoking you may have seen may have caused irreversible damage. If possible find a Computer shop near by that does micro soldering. they may be able to help and identify that chip for you. With that picture you posted I doubt that you will be able to resurrect that piece but do not loose hope! keep us in the loop!
