there might be no need for the old versions if there is one in mmxext,
looking at dsp_i386_mmx_init and dsp_i386_mmxext_init this is not the 
case for 
  funcs->restore_fpu = restore_fpu;
  funcs->sub8x8 = sub8x8__mmx;
  funcs->sub8x8_128 = sub8x8_128__mmx;
  funcs->sub8x8avg2 = sub8x8avg2__mmx;
  funcs->intra8x8_err = intra8x8_err__mmx;
  funcs->inter8x8_err = inter8x8_err__mmx;
