The following patch (against current CVS [1]) for style/beamer.sty
enables \subsection-like highlighting of \frametitle:

You may also add your own keywords as the manual suggests, but this is
done no matter if you actually use the beamer class or not:

,----[ (info "(auctex)Font Locking") ]

| (`font-latex-sectioning-0-face') ...
| `font-latex-match-sectioning-5-keywords'
| (`font-latex-sectioning-5-face').
`----

I.e. (setq font-latex-match-sectioning-3-keywords (list "frametitle"))
should do the trick, see `C-h v font-latex-match-sectioning-3-keywords
RET' for more.

Bye, Reiner.

[1] probably it wont work with AUCTeX <= 11.55 because some functions
    have been renamed.
