Not ediff, but I use this:

(defun tkdiff-buffer-with-file ()
  "Use tkdiff to compare the current buffer with the disk file contents."
  (interactive)
  (if (and (buffer-file-name)
           (file-exists-p (buffer-file-name)))
      (let ((temp-file (make-temp-file
                         (concat "/tmp/buffer-" (file-name-nondirectory
                                                  (buffer-file-name)) "-"))))
      (save-restriction
        (widen)
        (write-region (point-min) (point-max) temp-file nil 'nomessage)
        (set-process-sentinel
          (start-process "tkdiff" nil "tkdiff" (buffer-file-name) temp-file)
            `(lambda (process event)
               (if (file-exists-p ,temp-file) (delete-file ,temp-file))))))
    (message "Current buffer is not associated with any existing file")))
