that's a plus and a minus for us. It's nice seeing FILO get pulled into
supported software like Etherboot. But we've had uneven luck building a
working etherboot here. And ETherboot still does far more than we want. 

I would need to put the same kinds of mods into etherboot, and then build 
etherboot in a way in which all the ethernet support is not compiled in. 
In other words, I want to compile an etherboot down to FILO!

It is simpler to just use FILO directly.
