Setting the MAC Address in Mac OS

While Mac OS X.1 seemed to have no way to chenge the MAC address of the build in network interface of my powerbook Mac OS X.2 did a step in the right direction. By overhauling the Network Stack getting all the nice and new stuff like IPv6 and IPsec from FreeBSD they also added the lladdr parameter to ifconfig - but it seems there is still missing the driver support for it:

[bombadil:src/network_cmds/ifconfig.tproj] md% sudo ifconfig en0 10.0.0.1 lladdr 00:50:de:ad:be:ef
ifconfig: ioctl (set lladdr): Operation not supported

Any suggestions how to fix this are welcome.
