* check "if (model_id == NULL)" looks unnecessary now, since all
builtin model-ids are not NULL and user shouldn't be able to set
it NULL (cpumodel string parsing code takes care of it, if feature
is specified as "model-id=" on command line, its parsing will
result in an empty string as value).

v2:
  - afaerber: inline property definition inside of
              property array.
