Did you look at the source of switch-to-buffer?  This portion sounds
relevant:

      (let* ((entry (assq buffer (window-prev-buffers)))
	     (displayed (and (eq switch-to-buffer-preserve-window-point
				 'already-displayed)
			     (get-buffer-window buffer 0))))
	(set-window-buffer nil buffer)
	(when (and entry
		   (or (eq switch-to-buffer-preserve-window-point t)
		       displayed))
	  ;; Try to restore start and point of buffer in the selected
	  ;; window (Bug#4041).
	  (set-window-start (selected-window) (nth 1 entry) t)
	  (set-window-point nil (nth 2 entry))))))
