Ron that logic unfortunately does not work.

And stabalize the kernel so it properly shutdown the hardware I would be more persuaded. At least until I can get kexec into the kernel or we start a our own kernel tree for network booting and develop from there I am not especially interested in using the Linux kernel because it does not work correctly.
