Just a quick update.  With some very appreciated help from Sam Leffler, I've
now got my Atheros card working just fine with FreeBSD 6.1.  The part that
I was missing was to use wpa_supplicant to get the card to associate.  I
set the following in my /etc/rc.conf:

  ifconfig_ath0="WPA DHCP"

and created an /etc/wpa_supplicant.conf that looks something like this:

  ctrl_interface=/var/run/wpa_supplicant
  ctrl_interface_group=wheel
  ap_scan=1

  #
  network={
        ssid="OpenAP"
        scan_ssid=1
        key_mgmt=NONE
  }

  #
  network={
        ssid="PrivateAP"
        scan_ssid=1
        key_mgmt=NONE
        auth_alg=SHARED
        group=WEP104
        wep_tx_keyidx=0
        wep_key0=0123456789ABCDEF0123456789
  }

Obviously, I roam between a place that has an open AP and one that uses WEP.
