This issue is addressed in the NPPA/ IAEI book, "Analysis of Changes 2005 NEC. Pg 46, in discussing 210.52(C), and its' accompanying artwork, helps clarify that the area behind a range does not count toward receptacle requirements.
While it does not specifically address the matter of a free-standing range, I believe that the provision applies to ALL ranges- free standing or counter mounted.
But- why not install one anyway? Ranges used to have a convenience receptacle built in ( power tapped from range circuit inside the appliance). In many kitchens, this was the only convenience receptacle! At any rate, the cook will often wish to use a mixer, etc., while at the stove.
