Out-of-kernel-tree modules are still useful even if they are exactly the same license. I don't know what's with this tendency of having to put everything under the same umbrella. My modules will never get merged with Linux and I have no intention of doing so, but it is perfectly legal to distribute them with Linux (both are GPLv2). DKMS still helps to manage the mess that is the lack of a stable ABI for Linux.
