I pulled the latest sources from head and I can get the kernel to boot, but after it boots FreeBSD is unable to acquire an IP address.

That's not the main issue I have, the fact that the mac address is hardcoded.  The issue is once the RouterBoot loads and boots the kernel, I'm not seeing the kernel sending any DHCP/BOOTB requests down the wire, even though from the console log it is acting like it is.
