Obviously.  This works only with the patch I sent you.  But I asked you
to do on NS:

If with emacs -Q, you evaluate

(progn
  (setq frame-resize-pixelwise t)
  (setq frame-inhibit-implied-resize t)
  (make-frame '((width . 1200.0) (height . 600.0)
                (font . 
"-*-Courier-normal-normal-normal-*-17-*-*-*-m-0-iso10646-1"))))

what does

(cons (frame-text-width) (frame-text-height))

return?
