Hey thanks a million. That didn't exactly work but it, shot out a bunch of errors at boot, but it gave me the basis for getting it to work. I'm not good with shell script or anything yet, but after a little tinkering I came up with this, which works perfect for me.
Here it is incase someone else has this question (/etc/netstart)..
if [ "$if" = "INTERFACE" ]; then
ifconfig INTERFACE lladdr MAC_ADDY
# Now parse the hostname.* file
INTERFACE = the interface (rl0, eth0, etc)
MAC_ADDY = MAC address (format: 00:00:00:00:00:00)
It goes right after the creation of the interface and right before the parsing of the hostname.* files.
