Finding all the displacement in a scene?

Is there a simple way to list all materials and modifiers that are causing V-ray to attempt to render displacement?

I have a scene with Evermotion trees, and furnishings I’ve gotten off 3dsky. Some of these objects obviously have displacement enabled, and are causing my scene to run out of memory. Problem is, I can’t tell which without a big process of elimination.
I only want displacement on one or two particular objects. Is there a simple lister script or anything available?

Cheers

Yes, Collin has a script that I use for that.

+1 for Zorb, that script can do almost anything.
