It's still a pain to have to do this.  Many embedded systems that I have 
seen have a bootloader which I can't modify to do that, but the 
bootloader allows me to save the kernel command line into some kind of 
volatile storage.  Så being able to set the MAC address with a:

     setenv cmdline foo.hwaddr=00:de:ad:be:ef:ed

is very nice because it allows me to use a NFS root without having to 
jump through hoops with initrds an such.

Actually, I wish we had a generic way of doing that, so that could set 
the mac address of any ethernet interface from the kernel command in a 
nice and supported way.
