           struct  ether_addr      hme_factaddr;   /* factory mac address */
           struct  ether_addr      hme_ouraddr;    /* individual address */


the above is simply part of the softc equivalent for the solaris hme
driver.  it doesn't tell one anything about how to implement the
local-mac-addr for non-OFW/OBP machines.
