If you want to use three levels as frames in some places, I would
suggest you make all frames third level.  Second level headlines then
become subsections but you can actually skip form 1st to 3rd level
headlines and the beamer export won't care, e.g.

* section
*** a frame
*** another frame
* second section
** subsection
*** frame

I think you'll find it easier to simply have a consistent layout across
the document.
