OK.  I ws going by: 
http://www.centos.org/docs/5/html/Deployment_Guide-en-US/s1-networkscripts-interfaces.html

which says:

MACADDR=/<MAC-address>/

    where /<MAC-address>/ is the hardware address of the Ethernet device
    in the form /AA:BB:CC:DD:EE:FF/. This directive is used to assign a
    MAC address to an interface, overriding the one assigned to the
    physical NIC. This directive should *not* be used in conjunction
    with HWADDR.
