"... add-in card *or subsystem* ..."

I agree the spec could be more clear, and that it doesn't at all
give guidance on how these IDs should be used; but it certainly
does not say that completely unrelated devices should be assigned
the same subsystem ID, just because they are soldered to the same
board.
