Detecting if fullscreen is allowed in ActionScript 3.0?

Question

I would like to remove a fullscreen button if the allowfullscreen param is false.
      param value="true" name="allowfullscreen"

Does anyone know if its possible to detect that value? It doesn't come with other flashvars on loaderInfo.parameters.

EDIT: This is obsolete now (was a hack for FP 8.5 / 9)

The following will detect if your player has fullscreen availability (thx @mrdoob) :

var hasFullscreen:Boolean = (stage.hasOwnProperty("displayState"))
