What a pickle. You should be able to gain root access and fix this by:

1. Reboot the machine
2. When grub screen appears, press 'e' to edit the boot cmd
3. Append 'single' to the boot line, possibly after 'quiet'
4. Boot with Ctrl-x or F10.

This should drop you into a root console (no passwd needed) where you
can fix your group memberships. If it helps, your groups should look
something like:

corenominal cdrom floppy sudo audio dip video plugdev fuse scanner
bluetooth netdev cbnetwork

Hope this helps.
