When I first posted that response I was thinking that the scale that mattered was the compton wavelength of the particles being emitted, but having actually finished my coffee now I'm no longer so sure. My point was that so long as the horizon is sufficiently fine on the scale of the particle's compton wavelength then hawking radiation can still be emitted, even granted the horizon is not infinitely fine. This may be correct, or not.
