Sun systems generally get their ethernet addresses from the Openboot 
PROM and don't use the device ROM settings. It maybe that the cassini 
driver doesn't pick the right values up or maybe OBP isn't putting them 
there.

Can you get a prtconf -pv listing for you box. That will help to 
determine where the problem lies.
