Serial connection are most useful in these cases, but after the fact
this is not very helpful. I have also used cron jobs when doing remote
admin on machine with good success, if changing firewall configs, I
would revert he change and restart iptables, doing ssh configs same
deal.

Another good thing is to have a generic local account that has sudo
privileges assuming you have someone that can hope of the console for
you.

As long as the changes you made did not toast anything a reboot is your
likely only recourse.
