I guess the only way to fog/light these things correctly is to hand them to the right shader, but I only know how to do this for things which appear in effect files or which use one of the specified effects. I can certainly pick it up from there, but I had the impression that lights do not use terrain default, because I would have expected that to work consistent with the rest. Among other things, they would for instance get snow-covered or dirt-modified if they would use the terrain shader. So I think what I would need is the lights referencing some effect file if they're currently not sorted anywhere. > FYI, I've got a list as long as my arm of FG things to do, and have > struggled to find any time to spend on FG for the last month.

Probably on par with generating both tangents and binormals - it's down to looking up adjacent normals and computing how different their dot product with the local 'up' direction is. This shouldn't be outrageously expensive to do, but it would throw in some more non-local topology into the shaders.
