In spite of it saying your system is up to date, is it offering you any optional updates? Perhaps there's an optional update for a hardware driver you need to accept before it will offer you SP1.

I accepted an optional update for my Realtek network card last night and although repeatedly checking for new updates didn't show up anything else, lo and behold tonight it was offering me SP1. Could just be a coincidence though!
