Is it just a question of doing what it says in the manual, or is more
needed?

    The default behavior when a user drags files from another application
    into an Emacs frame is to insert the contents of all the dragged files
    into the current buffer.  To remap the `ns-drag-file' event to open the
    dragged files in the current frame use the following line:
 
         (define-key global-map [ns-drag-file] 'ns-find-file)

Maybe that change is sensible and safe enough for 24.1.
(I can't even test it so I wouldn't know.)
