There is only one person I know of who is restoring switches from miraculous states of f'ed up-edness. I think this person is only looking to work on "unique" situations at this point, but a method to restore is undoubtedly close. I had my switch restored by this person, and I can definitely say this process is not for the end user ATM.
**Edit** This definitely doesn't mean this is the only person whom can do this, just the only willing one I've found...
