Speculating, but I would imagine a good few months. I asked about this in the Discord a few days ago and was advised at least 14th gen (my N150) wouldn't be supported until the 7.1 release. If you were tossing up between waiting for an official release for support and trying FadedSun's kernel for example, I would probably recommend you don't wait if you can help it I managed to get my N150's hardware transcoding working for plex within like 20 minutes, super easy.
