Still I can't reproduce it on a Carbon build with my previous patch,
which is only for the dead-key cases.  Could you show a concrete
procedure starting from ".../Emacs.app/Contents/MacOS/Emacs -Q"?  What
I tried was:

  1) /Applications/Emacs.app/Contents/MacOS/Emacs -Q
  2) Evaluate (setq mac-option-modifier 'meta) and
     (global-set-key "\M-n" 'scroll-up) in *scratch*.
  3) C-h n to show Emacs News.
  4) Hold down Option-n for a second or two, then Option-v for a
     second or two, then Option-n again, etc.

I'm using Mac OS X 10.4.9, PowerBook G4, US keyboard layout.

Also, to make sure, please try some case that does not involve any
dead-keys.
