This happened to my 12" Powerbook. I took the foot off the other side so it didn't wobble and then moved on with life.

I mean, I really do understand your anger and frustration. But I've got to ask the question that: if it was Dell, Lenovo, Sony, Acer, Toshiba or whoever and they just turned around and said "sorry, don't have a part number for that", would you be just as angry?
