I didn't have to do that.

Yep, done that.

I deleted the old rule in there.

Aha!  Hadn't done that until now and I also deleted /var/run/wpa_supplicant/ath0

This has fixed it!  wpa_cli and wpa_gui now find my card.  Thank you
all for your help.

PS.  I noticed that unlike madwifi the in-kernel driver does not work
particularly well with iwlist:

# iwlist wlan0 ap
wlan0     Interface doesn't have a list of Peers/Access-Points

# iwlist wlan0 rate
wlan0     unknown bit-rate information.
          Current Bit Rate=24 Mb/s

wpa_cli thought shows the full list of APs.
