Impossible since the "fix" for Bug#15133.  Apparently no one used this
in the past four years.  Please apply the attached patch and try again.
The following example works here now as intended.

(customize-set-variable
 'display-buffer-alist
 '(("\\*text\\*"
    (display-buffer-reuse-window display-buffer-pop-up-frame)
    (reusable-frames . t))))

(setq display-buffer-mark-dedicated t)

(display-buffer (get-buffer-create "*text*"))

(kill-buffer "*text*")
