There is an undocumented ifconfig option that overrides the ethernet
address of the interface.  Sun uses this in their Sunlink DNI (DECnet
compatiblity software) product.  My guess is you can use it to make the
boards have whatever address you want.  Choosing a good address is left as
an excersize. :-)

The only documentation I've seen is in the installation scripts for DNI,
and all that stuff is at a client site that I can't get to anytime soon,
but the hint should help.

Suggest you get your Sun contact to dig up the details for you.  Another
thing to check is to see if you can find where they are setting the
addresses.  I'd guess that the boards have unique addresses burned into
them and they are having the default address loaded into them in one of
the boot scripts.
