I think network_interfaces and the autoloading support in ifconfig are
a massive mistake that we've been unable to kill.  The relativly large
amount of code you've written to hack around yet another edge case proves
my point. :) If you want to load if_iwn at boot just do:

echo 'if_iwn_load="YES"' >> /boot/loader.conf

and be done with it.
