I saw a bug report for this issue in Launchpad and it was a little worrying... It seems that the most that can be done is removing it from Jockey. They're not taking it out of the repos, because there might be an update yet.
Here is the "official" bug report in Ubuntu for this problem: https://bugs.launchpad.net/ubuntu/+s...73/+bug/948053
(Note: the bug report is that the drivers are uninstallable; NVidia still needs to upgrade them.)
Here is the bug report with nVidia: http://nvidia-submit.custhelp.com/ap...il/i_id/419011
(that might just be my account's link, I'll update it when/if possible if that's the case)
