Be sure to record all the needed data before doing this.
OldSun did not support or recommend this but the SE that taught one of my
hardware classes told the class how to do this.  (As described above.)  He
recommended capturing the hostid, mac address, etc. before doing this so
that it could be re-entered if necessary.  (License managers, and other
software, used the hostid for licensing purpose in the, thankfully, distance
past.)
anysystem.com probably sells the nvram modules also.
