Yep, I tried the dlight action with a cube.mdl, set its _range (skill4) pretty high and put it almost on top of the normal mapped model, then changed "faked dynamics" to false, and all I can get is the diffuse lighting from the material. I tried for hours.
Maybe there is something strange with either model? (the NM looks fantastic with faked dynamics on though).
In any case, if you could find time to insert a multiplier for the ambient (shadowing) and one for the power of the lighting, so the two could be adjusted (contrast?) for different environments, that would be super useful!
