It doesn't violate DFSG 9, because it's not making any claims on the other software. The advertising clause kicks in whether you distribute the software by itself, on a compilation CD, or whatever. Now, the advertising clause is GPL-incompatible, which is what I suspect you're thinking of with the "additional restriction" stuff. But lots of free licenses are GPL-incompatible.
