I don't get banding like that on my D1x. But I'm inclined to think it has something to do with the sensor. I would try cleaning, but I'm not sure it's going to take care of it, as it looks like a repeating pattern in a good part of the frame.
If you boosted exposure in a linear fashion beyond the dynamic range of the image, that might explain it.
