Clearing open firmware password

I have a G4 tower (dual 450 MHz, ADC graphics) that has the open
firmware password set.

http://docs.info.apple.com/article.html?artnum=106482

The hard has been wiped and due to the password I can't boot from a
CD, or clear the PRAM. The steps listed on the Apple page for
resetting the password require that you know the password. It also
mentions that you can bypass the password "Via physical access to the
inside of the computer." I don't see any jumpers that could be used
to reset the password. I've already tried removing the battery for a
few hours, but the password is still there.

Is there a way to clear the password, or it the system junk?

Remove a memory module. Turn on the computer and zap the pram right
away.
