I found the email where Alan announced this, but don't see a license off hand. I think it was a BSD-like don't-take-credit-don't-point-fingers-use-at-own-risk but don't see anything. Hopefully Alan isn't too sideswiped by this and can chime in.
As I recall with the announcement, one of the restrictions on releasing the source was that only the cg6 driver would be provided, since it was already part of the vendor SDK.
