The "Linux-only APIs" are a feature imposed by the Linux kernel developers, not by the GPL. Trying to circumvent it is of course contrary to the wishes of the Linux kernel developers, but that doesn't mean it's a violation of the GPL. The GPL does not say that no program that interfaces with a GPL-licensed work can do anything the authors of the GPL-licensed work don't like. It would be a violation of the GPL if NVidia tried to ship its own Linux distro including its proprietary drivers. But it's not doing that. NVidia doesn't ship Linux at all. Linux users install NVidia's drivers alongside the Linux that they install.
