Tricky router build

Hi!

Just got my hands on a couple of Socket S1 laptop processors, after going through the spec sheets a 25w Phenom 2 Tri core would be quite tasty on a mini itx router build. After the guys did the PFSense tutorial I started to use it and my router is currently chugging away on a full size Athlon64 x2. I'm having a hard time finding any boards that will suit this build though. Does anyone have any experience or information regarding this?

Thanks a bunch.
