Why isn't the ath0 card in promisc mode?  I thought it pretty much has
to be in order for the bridge to work (both NICs in my bridge stay in
promisc mode).

I'm not sure if you're using "device if_bridge", or "options BRIDGE",
but if it's the former, and you're running traffic through pf, take note
of the warning in the if_bridge man page:

The bridge may not forward fragments that have been reassembled by a
packet filter.  In pf(4) fragment reassembly can be disabled in the
scrub option.

That's just my guesses for places to look based on the info you described.

Cheers,
