as a wag, i would start by tweaking ether1116.c (sic) to leave the second port alone. remember that one disadvantage of socs is that there isn't a lot of discoverability. you just need to know what hardware you're running on. and touching stuff that's not there is often fatal. so, for instance, you may need to tweak the memory setup if you don't have exactly the same configuration of memory as the openrd.
