I've never tried to load this as a kernel module. It's probably better
to recompile the kernel with the right support. The ath driver also
requires ath_hal, which might be your problem.

You're obviously an old hand with un*x, but new to FreeBSD so in case it
helps:

#cd /usr/src/sys/i386/conf
#cp GENERIC MYKERNEL (or whatever name you want to use)
#vi MYKERNEL

add the lines:

     device ath
     device ath_hal

Make sure the following line is uncommented:

     device wlan

#cd /usr/src
#make buildkernel KERNCONF=MYKERNEL (or whatever you called it)
#make installkernel KERNCONF=MYKERNEL
#reboot

This assumes you have the sources installed.
