My girlfriends SM is a 51 cm 1st generation (pearly blue). AFAIK, besides the color change (to tiburon blue), the only other changes from 1st to 2nd generation San Marcos are to the fork: new fork legs with a more "classic" curve, and mid-fork eyelets, a la Riv.
I don't believe there were any other changes to geometry or clearance between the generations. The 650b and 700c San Marcos frames each have different tire clearances. The 650b fits a wider tire (stated clearance 38 mm) than the 700c (stated clearance 35 mm). In fact, the 650b still has pretty generous room with 650 x 38 tires, enough for 38 + fenders or for a 650 x 42 tire (Hetres at least, which don't have the extra thick tread of the Fatty Rumpkin).
