True, the serial number is not usually available to software.

All three numbers in the OpenBoot banner are derived from one,
the hostid.  The S/N and hostid are the same number, one printed
in decimal, the other in hex.  The Ethernet MAC address is also
derived from the hostid.  The hostid is unique amongst all Sun
computers but is not the same as the system/chassis serial number.
