Here's the other way to do it...

git clone git://git.linaro.org/people/dmart/tunsetup.git cd tunsetup make sudo ./tunsetup -c -t tap -o `id -u` tap%d >/tmp/tunsetup.conf # ^ this creates a fake ethernet device which can be accessed by you

. /tmp/tunsetup.conf -C motherboard.hostbridge.interfaceName=$TUN_IF

Random link-local addresses are generated automatically. You can configure boot-time networking on the model by putting:

ip=$TUN_REMOTEIP::$TUN_LOCALIP:$TUN_NETMASK

...on the kernel command line

If you want to allow the model to talk to the Internet, you also need to enable NAT:

sudo /bin/sh -c 'echo 1 >/proc/sys/net/ipv4/ip_forward' sudo iptables -t nat -A POSTROUTING -s $TUN_REMOTEIP -j MASQUERADE

...and copy/paste the contents of /etc/resolv.conf into the model filesystem's /etc/resolv.conf

The IP and DNS setup stuff could be handled by having a local DHCP server, but I was too lazy to set that up...

Let me know how you get on!
