Most of it can be done in the GETPOS macro, and require very little 'code' changes.  Md5_gen already had arrays of MMX_COEF items, since I found it was faster to load a dozen or so of them (actually, 32 or 64 for mmx_coef=2 was a good count).  Since that double dim array was already setup, it made hooking in the intrinsic code very easy to do.  It is a little slower, in loading.
