the Linux kernel actually can make up a mac address for you, there is even a standard call to do so. we don't officially support eepromless designs in our normal drivers (most embedded users expect to modify their drivers). I know that there is some test patches to allow the eepromless set up in our drivers, that our TME teams have been working on. >> [snip] >>> To date, the only way I've seen around this is to just hack out the >>> code in the e1000 driver that deals with the EEPROM and MAC >>> addresses.

That would definitely be something specific to your setup since it is handled by redboot.
