This is just in addition to their current business of selling chips and cards as far as I can tell. I don't think anyone will want to produce exactly an nVidia chip, most likely the idea is that other vendors would want to integrate an nVidia GPU core on their mobile SoC (Kepler as an architecture is supposed to scale from mobile to cluster computing sizes) - perhaps Qualcomm or Apple, or hell, maybe even AMD now that they're starting to put out ARM chips. Heck, it'd be pretty interesting if Intel put integrated Geforce cores on their next gen CPUs, at least as an option. Although most likely neither AMD nor Intel would bother since they've got their own fairly strong mobile GPU architectures now and figuring out how to integrate an nVidia core would probably be more work for dubious gain.
