Remember Kororaa? (Score 1)

The kororaa project made a live-cd with linux, x11 and proprietary drivers for video cards from nvidia and ati. They stopped distributing it because som kernel devs claimed it was a violation of the GPL to distribute GPL software and GPL-incompatible software on the same media. That sounds like what you were planning on. Also, i think that you are not allowed to link statically to GPL'd code, not sure about LGPL either. You can link dynamically to LGPL though. see http://kororaa.org/static.php?page=gpl
