About all you will be able to do is raise the FSB. On my old 3200 I ran at 222x11 @2442 for 2 years and my Mom is still running it at 210x11 @2310 for the last 2+ years (she's an OC'er and doesn't know it LOL).
The 6800 was known for running hot,hot,hot but still may have a little extra left in er'.
As for the Hyena, it may not be generic, but it's really close to it. You may want to check around to see if you can find a back-up laying around.
