Perhaps the solution is to do a (restart) in your hook :)

Now, seriously. When I was trying to get this code completed I
discovered that the configure-notify-hook
is called when the root window is resized (and any other window).

One way to catch the change of resolution in a hook is to compare the
parameter of the hook to
'root:

(defun dmg-rotate-hook (w)
  (if (equal w 'root)
      (dmg-after-rotate)
    )
  )

One thing I didn't do was to pass parameters to the hook. At this
point I am not sure what is important/needed.
