QEMU + FreeBSD

[Jim]

I have installed FreeBSD 7.2 on my notebook in the last week, and
installed QEmu as well.

I cannot seem to get the network interface working. It works on my
desktop machine, but that is running 7.0

looking around, I tried to find some other options, and went here:
http://wiki.freebsd.org/qemu

and got stuck at this step:
 # sysctl net.link.ether.bridge_cfg=fxp0,tap0
 # sysctl net.link.ether.bridge.enable=1

because nothing matching "net.link.ether.bridge*" exists.

Does anyone know of a current good setup document?

thanks,
