I have made some headway... The attached stub appears to work but in my
limited testing so far, it may be a bit unstable. The driver stub is for
FreeBSD 4 (tested on 4.9) and I may work on a 5.3+ one soon.

YMMV. Use with caution...

Simply copy the attached files into the same directory that the kqemu
distribution is untarred and build with

# make -f Makefile.bsd

Install  with

# make -f Makefile.bsd
# kldload kqemu

You will need to create the /dev nodes

# mknod /dev/kqemu c 250 0 root:wheel
# chmod ug+rw /dev/kqemu
