What would happen if NVIDIA used this define in their proprietary

may be about to use a product that may be doing this very thing. We had
to sign a license agreement to get the kernel driver source for this
product. What we received contained the kernel driver source and user
land library stuff. The source code for the kernel driver has
MODULE_LICENSE("GPL") defined. The only license info in the package
received was NOT the GPL license.

On this particular vendors web site they offer unrestricted downloads of
binary packages for their product/s that are for specific DIST kernels.
But to get the source requires signing a license agreement that is NOT GPL.

There are two cases.

1) They're using GPL-exported symbols in a module that they're trying to claim is not licensed under the GPL. In this case someone with suitable copyright standing could talk to them and get them to release the code or rewrite it to not depend on GPL-only symbols.

2) You want to use their code under the GPL. In this case you should probably talk to your legal people. If you released the code under the GPL and they sued you for it you might be able to argue that that statement implies that the module is licensed under the GPL. But it might be an expensive argument.
