The appears to be yet another duplicate of Bug #728745 and others. But this is not upgrade issue. It is a problem for certain nvidia cards that has been there since alpha and is sadly still in the release version from a fresh install. I have heard it maybe an nvidia driver issue, but that does not explain the disappearing Nouveau entry in the jockey driver list.
