I doubt there are many "pure" 3dnowext functions in there, most of these
functions  were MMXEXT  functions scheduled  for K7  pipelines  (see the
header comments of 3dne files).

Applied proposed fix until we sort which's which:

2004-04-07 22:30:15 GMT patch-9

    Summary:
      3DNow Ext functions use MMXEXT opcodes.
    Revision:
      xvidcore--stable--1.0--patch-9

    From Soltius (XviD Forum):
     * Most of 3dnow extension functions do use MMXEXT opcodes, so
       classify these functions as 3dnowext+mmxext. Avoids K6-2
       boxes to crash with an invalid instruction error reported
       by the host OS.
