There's a number of different options for this. By far the easiest is
to create a rc.d script and place it in /etc/rc.d or
/usr/local/etc/rc.d. You can load firmware and do whatever else you
need to do there.
Another alternative is to hook into devd and have a script run when
the driver attaches. This would have the advantage of running
automatically when you load the driver as well as at boot.
IF all you want to do is load firmware, you can use techniques similar
to isp and ispfw to place the firmware in a module that's loaded as
necessary to load the device's firmware.
