Any issue like this that I've seen has been the result of a texture or teture-mapping issue. It usually happens when the part of the texture that's mapped to the middle of the face is on the extreme end of one side of the texture, the hair part is on the extreme end of the opposite side, and the mapping doesn't actually overlap but it's very close to doing so. While there's no error here technically - the head will seem fine in Max and even in NWN if you're zoomed in close - when you zoom out in NWN the line will appear. I think this is due to the way the game blends pixels when you zoom out - because the texture is treated like a tile, the (say) leftmost part of the texture is regarded as right beside the rightmost part, and so the skin from the middle of the face will blend with the hair (which is usually darker than the skin).
The way to fix this is to make a bit of a "buffer" at the edges of the texture and move the edge t-verts in a bit. If I was on my own computer, I'd post an example picture. If my explanation here isn't clear, I'll post a pic when I get back to my computer.
