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.

Unfortunately the mac address is hardcoded for this driver (in sys/mips/adm5120/if_admsw.c):

 389         /* XXXMIPS: fix it */
 390         enaddr[0] = 0x00;
 391         enaddr[1] = 0x0C;
 392         enaddr[2] = 0x42;
 393         enaddr[3] = 0x07;
 394         enaddr[4] = 0xB2;
 395         enaddr[5] = 0x4E;
