If you are using a custom kernel, you can add that to a file and add 'env /path/to/file/on/build/host' to the kernel config to wire that into the kernel, should the boot path make it hard to set an initial environment otherwise. Also, DHCP should still try to grab /boot/loader.conf from the tftp/http server as well. That might also be something that needs debugging (or hopefully just correct config).
