I'm in no way a licence expert and I'm not a FreeBSD developer, however
my understanding (from sources such as
[http://wiki.freebsd.org/VendorInformation])
is that in answer to your original questions
a) Device drivers - yes but it cannot be included in the GENERIC config,
but thats what modules are for anyway.
b) Kernel/base system - No - I belive this would need to be BSD licensed.
c) userland - Yes but probably needs to be in the contrib directory

as an example, all the ZFS stuff is CDDL licenced , This had to be kept
separate from pretty much everything but it's there.
However I could well be wrong and its almost certainly worth asking
these questions again on the freebsd-current mailing list where
developers who might actually know the answers hang out.
