I am chiming in a little late here, but...

Try out Todochiku, which is a notifications package I wrote for emacs:  http://www.emacswiki.org/emacs/ToDoChiKu

It works with appt (and thus with org mode) and it is compatible across different notification programs (and OS).  It has a customization option todochiku-appts that will set up a growl notifier as your appt-display-function.

Enjoy.

Thanks for this, this'll prove handy at work.  I took the liberty of 
simplifying the elisp a little.  This version doesn't create a temporary 
file, and instead uses a shell HEREDOC.

(defun output-to-growl (msg)
     (shell-command (format "osascript <<ENDSCRIPT
tell application \"GrowlHelperApp\"
      notify with name \"Emacs Notification\" title \"Emacs alert\" \
        description «data utxt%s» as Unicode text \
        application name \"Emacs\"
    end tell
ENDSCRIPT"  (osd-text-to-utf-16-hex msg))))

(defun osd-text-to-utf-16-hex (text)
   (let* ((utext (encode-coding-string text 'utf-16))
          (ltext (string-to-list utext)))
     (apply #'concat
      (mapcar (lambda (x) (format "%02x" x)) ltext))))
