Actually, FireFly does 32bit float displacements. The 8bit limitation right now is in the image map node. It's easy to see when you use a procedural texture for displacement (most, if not all procedurals work with 32bit floats). How to combine two 8bit images into one 16bit image in the material room has been demonstrated on various occasions, btw.
