There are `prev-buffer' and `next-buffer', bound to C-x <left> and
C-x <right> respectively, in the development sources:

(define-key global-map [?\C-x right] 'next-buffer)
(define-key global-map [?\C-x left] 'prev-buffer)
(defun next-buffer ()
  "Switch to the next buffer in cyclic order."
  (interactive)
  (let ((buffer (current-buffer)))
    (switch-to-buffer (other-buffer buffer))
    (bury-buffer buffer)))

(defun prev-buffer ()
  "Switch to the previous buffer in cyclic order."
  (interactive)
  (let ((list (nreverse (buffer-list)))
	found)
    (while (and (not found) list)
      (let ((buffer (car list)))
	(if (and (not (get-buffer-window buffer))
		 (not (string-match "\\` " (buffer-name buffer))))
	    (setq found buffer)))
      (setq list (cdr list)))
    (switch-to-buffer found)))
