That may be true for specific features like Optimus--I can't say. But if you're talking about writing a full 3D driver stack for a modern GPU, you're almost certainly underestimating the effort involved by several orders of magnitude. NVIDIA has hundreds of full-time software engineers working on the various parts of the GPU driver stack. Now imagine doing it without the immense institutional knowledge.
