I would like to have a check for a family at the beginning, something like:

      if (name == signature_NSC_ebx)
    processor = PROCESSOR_GEODE;
      else if (family == 22)
    {
      if (has_movbe)
        processor = PROCESSOR_BTVER2;
      else
        processor = PROCESSOR_BTVER1;
    }
      else if (has_avx2)
        processor = PROCESSOR_BDVER4;
      else if (has_xsaveopt)

Please also fix ChangeLog entry.
