Normals would give you different results, the sadows would be different, as well
as the continuation between the different surfaces. That's even if you apply the
normals to the object as a whole. Even at this scale you'd have large difference.

I think Tim gave you the best solution to your problem, so I'll take
this opportunity to slip out the door :)

I think I'm going to give up on the isosurface room. Rendering takes way too
long especially with area lights and radiosity. On the other hand, I did get to
finally learn how to use these things.
BTW, is there an isosurface to mesh2 conversion utility?

There's Kevin Loney's Approximation Macro. It's rather slow but you only
need to run it once, then you can save the mesh.

If you can rewrite your isosurface as a parametric, then you can use
Ingo Janssen's Param.Inc, which is much faster.
