but ndiswrapper isn't static linked

atheros IS a problem.

For static linking to GPL? I've not even found a single lawyer who
thinks there is a gray area there. Dynamic linking to the kernel.. yes.
But not static linking.

actually the test here is not "derived work". Derived work matters for
clause 3 but not for clause 2. That's where there is a difference
between static and dynamic linking. Static linking doesn't "need" the
derived work part.

And there is a gray area on at what point something stops being for
another OS... like how much are you allowed to change/add in other code
(and mind you, the "glue layer" then cannot be GPL or you violate clause
2 again, so if your glue layer is derived you have lost again anyway)
