That is probably not what their meant, but if you are able to exploit the blob of the nvidia driver, then yes. But you are already able to load a module into the kernel, then you already have root level access and other, easier, options are open for you. Because modules can be easily listed and therefor monitored, a change of the modules could trigger an alarm to the admin. So it isn't really stealthy either.
