It looks as though the e1000 driver doesn't support changing the MAC address.  
The e1000 driver is a (dubious quality) port from the Linux driver, and it 
looks as though the part that sets the MAC address registers is called at 
device creation time rather than at device open time.  This means that 
changing net0/mac will have no effect.

Patches (or complete replacement drivers) are welcome!
