To reset Open Firmware:

Reboot while holding Command-Option-O-F
Type reset-nvram <Enter>
Type set-defaults <Enter>
Type reset-all <Enter>
Type mac-boot <Enter> (depending on which firmware revision you have, this
may not be necessary)

Replacing the FireWire chip may be something you want to try, but unless you
have experience with soldering surface-mount components, you'll probably
just end up buying a new motherboard anyway.

Good luck,
