Ive done some more reading, and i think prepacking AMD or NVIDIA drivers without a redistribution license from the vendor could land you in hot water.
You may not have AMD or NVIDIA lawyers on your case today, but this is inevitable.

I hope that the community can continue to package AMD and NVIDIA binaries without fear of legal repercussions.
I will contact AMD & NVIDIA by email to determine if one can obtain a redistribution license gratis for the purposes of selling more AMD and NVIDIA products.
