None of them do, because Sugar can be used on hardware which does not
provide a serial number, and more than one instance of Sugar can be
used on devices that do provide a serial number.  You must find
another way to ensure uniqueness, such as registration to a central
authority database.

The aboutcomputer control panel section contains legacy code specific
to the OLPC XO laptop.  You should not design on that basis alone.
