Actually,

(info "(preview-latex) Misplaced previews.")

applies here.  While it is conceivable to create a beamer-specific
preview-latex configuration file
prbeamer.cfg
and let AUCTeX add a "beamer" argument to preview-default-option-list,
one would need to decide whether frames should be displayed as a whole
(\PreviewEnvironment{frame}) or just dissected into parts
(\PreviewEnvironment*{frame}).
