Thanks to Justin Stringfellow.

I had patched the system when it wasn't properly in single user mode.
I typed 'init s' while in run-level 3, but it seems that rebooting to single user
mode is the only way to guarantee that you are really there.

The recovery involved finding the affected file in the patch, putting it on a tape,
booting into single user mode from CD, mounting the filesystem and replacing the
affected file using the one on the tape.

This worked great and only took about 5 minutes.
