Yeah, the Faux Bold thingy won't let ya warp text so what I do is to put a black stroke (or whatever color your text is) on it to fake a faux bold and still be able to warp it to a path. The caveat is that the fatter the stroke the rounder the pointy bits get so use a small stroke. Strokes also disrupt things like outer glow and drop shadow so if you are using those then duplicate the layer and put the stroke on its own.
