That would be really fine, because if there are some differences we need to find 
a way to get the source working on both hardware revisions.
We could use for that reasons a new CONFIG entry in the Config.lb, but 
hopefully we won't need that stuff.

Fine, that's nice to know, i just looked in the source and saw that the MAC-
address is set in romstrap.inc under 
src/southbridge/nvidia/mcp55/romstrapc.inc.
So one TODO is already done, the others should be also easy to clear if 
someone could send the output's which are necessary to verify from a v1 board.
I mentioned those things in the first mail according to that patch.

Maybe it would be good to add a configuration-field in the buildrom-devel to be 
able to set this before building the image.
