Mwah, this seems to work:

(setq header-line-format
      (concat "ss"              ; To cover my scrollbar.
              (propertize "f"   ; To cover the fringe.
                          'display 
                          `(space :width ,(/ (float (car (window-fringes))) 
                                             (frame-char-width))))
              "hello world"))
