The main question here is who will be developing the driver. It should
be someone with time, interest and access to the hardware and their
specs. It is probably easier if you're willing to do it, as you have
already what is needed. People at this mailing list can help you by
reviewing the patches once done, pointing you on how to correct things
that are not ok.

If you're not willing to do it yourself, then you'll likely need to 
sponsor someone to do it (either finding a hobbyist and donating him some
hardware or hiring some professional).

The need of a NDA can make it harder for hobbyists, as several won't
sign such documents. Also, the NDA should be carefully written to
allow to release the open source drivers after the job is done.
