AFAIK, this is not correct.  It is totally feasible to use a MAC address that
is derived from the machine id, as long as it is guarranteed that this is
indeed a valid and reserved MAC address. E.g. SUNs have always used the low
24 bits of the machine id concatendated to SUNs own registered 24 high bits
(08:00:20) as the MAC address for all ethernet interfaces in a machine.

I remember people reporting problems when they, for some reason I cannot
remember now, wanted to connect two interfaces of one machine to the same
ethernet. I don't know how, if ever, this got resolved.
