You need to set the tunable debug.wpi before loading the module.  Set it 
to 0x82, enable bootverbose and then load the module.  I see you also 
don't have the revision D hardware, which is the only one the driver 
actively knows about. 

It's also interesting that all the A channels are listed as being passive, 
what regdomain do you have set (ifconfig wlan0 will say)?  You could try 
changing the regdomain (IANAL) and see what happens.
