OK, I've now taken this and the other FreeBSD patches, added a few
small ones of my own and made a port, it can be fetched at
        http://www.freebsd.org/cgi/query-pr.cgi?pr=67506&f=raw
(and hopefully will be committed soon.)

 I've noticed the following things tho:

- needs to run as root in order to use /dev/tap* networking (why?)
- slirp (usermode networking) compiles but doesn't seem to work for me
- seems to have a timer problem (time sleep 1 takes 49 seconds and
booting sleeps for minutes at the acd0 probe), but only on _some_ guest
systems (FreeSBIE, knoppix.)  An installed 5.2.1 guest system works ok
(this also doesn't happen with linux as host.)  And enabling /dev/rtc doesn't
help either... (not included since it needs a patch to emulators/rtc.)
- using physical media doesn't work on 4.x hosts (missing DIOCGMEDIASIZE
ioctl)

 Testers and anyone who has ideas about these problems welcome...
