Hmm, how about:

(defvar my-flag t)

(setq mode-line-format (copy-sequence mode-line-format))

(setcdr (nthcdr 4 mode-line-format)
        (cons '(:eval (if my-flag " True" " False"))
              (nthcdr 5 mode-line-format)))


It seems like an odd way to modify the mode-line, but I can't think of
any better right now.
