Turns out that there is a page on the wiki that has some good
suggestions, although it could use a bit of tweaking. I got networking
up by doing this in the host:

myif=bge0

ifconfig tap create
ifconfig bridge create
ifconfig bridge0 addm tap0 addm $myif up

Then I was able to start qemu with the tap command line and now
networking works.

I also installed kqemu, but I'm noticing that even with that working
it's still pretty slow. I have a pretty fast core 2 duo and qemu is
often pegging one of the cpus. Still, it's interesting enough to keep
trying to make work ...
