You're by any chance using dynamic DHCP to acquire the addresses? If so,
beware that the BOOTP code in the kernel is working ONLY with BOOTP. In
this case, insert a record like
	host xyz{
		hardware ethernet 00:00:b4:6b:21:8f;
		fixed-address x.y.z.q;
		.................
	}
in your dhcpd.conf.
You can also make your image with 
	mknbi-linux -i rom  .............
so your kernel uses the data acquired by the bootrom.
