Chad, I have a first generation 52 Bombadil, and currently have Quasi-Motos mounted on Synergy rims on it. I think they fit fine at the pressures I usually run in them (20-25psi). If I recall correctly, when I first mounted them I seriously over inflated and the resulting clearance was minimal to inadequate. I don't think I would buy 2.1 MTB tires for it, though before I bought mine I rode a demo at RBW WHQ that had (I think) a Quasi on the back and a Fire Cross (bigger knobs so fatter) on the front. As others have noted the later Bombadils (diaga tube/stays and different crown) have more clearance. I don't know if some of the later parallel top tube versions had more clearance than the earliest ones or not. I fear if you want to use most current 27.5 MTB tires the early Bombadil may not work to work.
