Nope, doesn't make a difference.

But Drew's suggestion to bind `echo-keystrokes' to nil helps.

Interestingly, the following menu item shows the problematic echo  
message. When I bind  `echo-keystrokes' to nil, I get the "One-Buffer- 
One-Frame-Mode dis/enabled" message which is output by what menu-bar- 
make-mm-toggle produces. So it seems like the keystroke echo message  
even overwrites the previous (much better) message.
The menu item I'm talking about is defined like this:

(define-key-after menu-bar-options-menu [oneonone]
      (menu-bar-make-mm-toggle
       one-buffer-one-frame-mode
       "Display Buffers in Separate Frames"
       "Open a new Frame (window) for each new buffer."
       (:visible (boundp 'one-buffer-one-frame-mode)))
       'edit-options-separator)

Other entries, e.g., save-place, behave differently. Here, the "en/ 
disabled" message appears after the keystrokes echo. This one is  
defined with `menu-bar-make-toggle' (in menu-bar.el) rather than with  
the minor-mode version.

Note that the minibuffer must be empty to reproduce this (see use of  
Vecho_keystrokes in the code).
Of course, the echo-keystrokes solution can't be the final word for me.

Echo-keystrokes is meant to be for unfinished keyboard commands. The  
menu item selection is a finished command, however.
Does it behave like this in other ports (I'm a Mac guy) as well?  
Sounds almost like a bug in either the Carbon port or even in the  
general implementation.
