This looks like a longstanding bug in handling modules loaded by loader 
that have undefined references (e.g. because your kernel is misconfigured).

In general I don't think you're going to get very far booting a HEAD 
kernel against RELENG_7 world.  This will certainly not work for 
wireless where you need all the changes to ifconfig.  If you're trying 
to test HEAD you will want a separate partition with a fresh 
install/build of HEAD.
