One approach would be to navigate the series of function calls defined
in /etc/network.subr. I just took a brief look, but it's not immediately
obvious how many times you're going to have to escape exactly what to
get the behavior you desire.

Another option would be to make the file /etc/start_if.ath0, containing
the line `ifconfig ... ssid "my network"`. This file would be sourced
when /etc/rc.d/netif starts the network interfaces, before the rc
variable ifconfig_ath0 is run. You can then omit the variable
ifconfig_ath0 from /etc/rc.conf.

For more hints, look in /etc/netif, /etc/network.subr, and /etc/rc.subr.
