Hmm, it should have at least helped.

I was wrong about POV-Ray not mapping the gamma correctly: it does. Also, when
trying to re-render the height map in POV, you need to use "interpolate 2" in
addition to high AA settings.

Try the attached. It's just a simple blur filter, but it works for the tiny
portion I cropped from your image.

Failing that, try the blur/resample file a posted a while back:

You might want to render your map at 2x resolution with a decent amount of blur
(2-6), and scale it back down to its original size.

If none of that works, would you mind posting your entire height map so I can
figure out what's going wrong?
