I looked into the lens models in some detail a while back, and they are not the same. Adobe is using r^2, r^4 and r^6 distortion coefficients, plus tangential distortion. This is likely identical to Bouguet's camera calibration, at http://www.vision.caltech.edu/bouguetj/calib_doc/ Hugin uses r, r^2 and r^3 distortion, and no tangential distortion. Hugin also uses a different normalization of radius, so the 'r' terms are not the same, although you can convert. It is possible to get equivalent answers from Hugin and Bouguet if you restrict to the r^2 term only, but that's not necessarily powerful enough to handle the distortion in a typical point-and-shoot, or wide- angle lens.
Adobe doesn't directly reference Bouguet, though, so it may be one of the variants.... Sorry, not a simple answer, and not really complete. I never wrote up properly what I found.
