I had installed virtualbox-ose to see if I liked it (I did), but decided that I wanted the full version, so I installed Sun xVM VirtualBox and loved it even more. Having the better version, I removed the Virtualbox- OSE, which deleted the vboxusers group, which caused these symptoms on my system. I manually recreated the group, added myself and root to the group and did a /etc/init.d/vboxdrv setup and it fixed everything right up. Hope this helps someone.
