Comment 2 for bug 811097

If you want to uninstall virtualbox-ose try this:

- entry in the system using recovery option
- use netroot option (console with user root and networking).
- use dpkg -P virtualbox-ose, to purge the packages

This works for me, I think that if you entry in this way in the system, vboxnetadp module is not loaded and you can perform the uninstall
