Verify you have the latest HAL using

sysctl hw.ath

The version should be 0.9.5.3 or better (can't remember if I committed .4 
or .3).  If you have an old version update.  Otherwise you might try 
tapping 802.11 frames with tcpdump on the AP to see what's going on:

tcpdump -i ath0 -y IEEE802_11

As to dstumbler, it is intimately tied to the wi driver at the moment.  I 
have a version that works w/ wi and ath drivers but it's a major rewrite 
and incomplete.  If someone wants to pick it up I'd be happy to pass the 
(incomplete) work on...
