I have B7.1 Pro on a Win XP 64 machine.  I went back and checked.  I can add displacement to a stone or bryce boolean object if I wait for the preview to render like you described.  But even the preview would crash my machine if I tried it on an imported object.  See my recent gallery post that I wanted to add displacement to enhance the cracks.  Maybe it has something to do with procedural mats vs picture based mats or how more complex objects are rendered.

I would like to add a displacement map (or something like that) made from a Bryce terrain onto a second Bryce terrain.  Say a 'mordor' fractal terrain mapped onto a 'zorch' to simulate wind ripples on an ocean wave.  This is what I mean by terrain on a terrain.

Maybe this all can be done and I haven't figured it out yet.
