You should have the following kernel modules loaded:

# kldload kqemu
# kldload if_tap
# kldload aio

Then you may either used a devd hook to ifconfig the interface or (as I
do) start 'qemu' as root. It will execute a shell script when it brings
up the interface as:

$ cat /usr/local/etc/qemu-ifup        
/sbin/ifconfig $1

(for the 'ifconfig' you must be root, or use devd hook, or 'sudo' in the
script). That's all. Set the other end of the NIC in the guest system to
IP end the communication with the host OS (your FreeBSD 7.2)
should be fine. 

To reach the outerworld from the guest, I'm using NAT in the host OS.
Check the FreeBSD handbook how to enable this.

People who hate Microsoft Windows use Linux but people who love UNIX use FreeBSD.
