 *real* key column of the GRASS vector's dbf table. In case of the example
 vector map the key column is *cat*, not *name*.

 I don't see the problem here.  In the identify dialog you don't see the
 key at the top, you see the display field.

 And QGIS selects the first field which field name contains {{{name}}},
 {{{descrip}}} or {{id}} (in that order).  If there is none it takes the
 first field.  See QgsVectorlayer::setDisplayField().

 So there's no relation between the key and the display field.
