Jostein, I am not Mark, but I have used several lens reversed with the D and have gotten decent TTL exposures. I have used a Vivitar 28.2.8, a Pentax A 50/1.7 and Canon FD 50/1.8 reversed on the D. I have even used these mounted on bellows and have managed pretty well.
You are correct that these combinations will lead to extreme overexposure under default conditions. However, I have found that you can dial in enough compensation so that position/distance changes will lead to correct TTL exposures.
