For this reason I have

PORTS_MODULES=emulators/kqemu-kmod

in /etc/make.conf so that it gets rebuilt when I rebuild the kernel.

Actually it does.  See /usr/local/share/qemu/pxe-* but due to
at lease one bug it doesn't work.

I found and fixed one bug in src/core/osloader.c (in
etherboot-5.4.3 code) which allows me to get a little bit
further.  If anyone wants to play with this more, I can send
them my changes.
