hw.ath mib entries define values used to initialize each new ath device. 
  You cannot set regdomain (yet) but countrycode can be overridden by 
setting hw.ath.countrycode before loading a device.

Note this says channels 8 and 12 are capable of 11a which is nonsense. 
Looks like a hal regdomain problem, probably related to the addition of 
turboG (turbo+11g).  For now you'll need to lock the channel to your ap 
or filter out 8+12 using something like

ifconfig ath0 chanlist 1-7,9,10,13-46

(13-46 is ok as unavailable channels should be silently ignored).

I'll try to look tomorrow.  I have a patch for fixing wep with ndis that 
I need to review and this is probably the same thing.
