Perhaps something like this (untested)?

(defun my-ediff-revision ()
  "..."
  (interactive)
  (find-file (expand-file-name
              (file-name-directory (ediff-get-default-file-name))
              (if ediff-use-last-dir
                  ediff-last-dir-A
                default-directory)))
  (when (and (buffer-modified-p)
             (y-or-n-p (format "Buffer %s is modified. Save buffer? "
                               (buffer-name))))
    (save-buffer (current-buffer)))
  (ediff-load-version-control)
  (funcall (intern (format "ediff-%S-internal"
                           ediff-version-control-package))
           "" "" nil))
