I think that the mac address of the dm9000 is on the eeprom. Linux write 
it using
ethtool. Take a look at the dm9000_write_eeprom in the linux code. I 
think that if you want
to use enviroment variable of u-boot, you must write in the eeprom only 
if the value is different
from the enviroment variable.
