Sorry, just getting back to this post-holiday.
I'd compiled the whole with "make DEBUG=undionly:3,undinet:3,pxeparent:3" for both undionly.kpxe and .kkpxe as well, tried both through multiple reboot cycles.

Most times it all just works. Occasionally, however, it just hangs after passing device initialization, at the "control-B" prompt.
