Corrupted DB - Help

Running postgres 8.1.2 on gentoo linux 2.6.14

Server crashed (not sure if due to pg operation).  Upon rebooting server and trying to start postgres, get the following log entries:

The last commmand that I did right before the crash was a vacuum full on a very small table.  After it completed, I exited psql, tried a non-pg command and it hung up.  Here are the last log entries before the crash:

Any way to salvage this db?

Thanks,
