[beagleboard] BBB can't connect over eth0

I have two beaglebone blacks. One is working fine, the other isn't; as far as I can tell, they are nigh on identical (both Rev C--not sure what else to look at; I did get the nonfunctional one more recently and possibly from a different vendor). I've tried both BBB's booted off of the same mic
