Can you please test with (CVS) Emacs 23 whether

(defun x3 ()
   (interactive)
   (let ((undo-inhibit-record-point t))
     (delete-backward-char 3)
     (setq buffer-undo-list nil)
     (insert "A")
     (message "%s" buffer-undo-list)))

does what you want here?  If it solves your problem then we probably
should consider a solution like the one I sketched in
