why not add the ethernet address to the ifconfig in /etc/rc.local ? there
are several lines calling ifconfig in there, and ifconfig accepts new ethernet
addresses to change to. if the underlying ioctl call is bad, though, this may
not help, but it's worth a try.

i installed sunlink dni (decnet software) on our suns and needed to change
the ethernet address to correspond to dec's configurations. this worked fine.
