It looks as though you haven't loaded all the madwifi modules in the proper
order.  modprobe will sort out the dependencies and load everything you
need, while insmod will not.  Have you applied the patches for AR9285
support?  They are available as attachments to the ticket here:
http://madwifi-project.org/ticket/2391

The AR9285 is not supported in trunk yet.  I would guess that once you apply
these patches, rebuild, and reinstall, then modprobe should work just fine.
