You have a sensible legal department. Many hold that distributing Linux kernelspace code under a non GPL compatible license is illegal, period. Your job, should you chose to accept it, is convince them that releasing the code you will be writing under a GPL compatible license is not actually all that scary. Pointing them to all the other companies that do so can help. The other option you have is make do without _any_ help from _anyone_ on this list at least. Good luck.
