I have the atheros chipset too in one of my PCs (a desktop, using a
Netgear WPN311). This is how I got it working. There might be a clue
in here that will work for you. The following is what my
/etc/wpa_supplicant.conf looks like:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=2
fast_reauth=1
network={
        ssid="YOURSSID"
        proto=WPA
        key_mgmt=WPA-PSK
        pairwise=TKIP
        group=TKIP
        psk=GENERATE THIS LONG STRING WITH WPA_PASSPHRASE
}

In etc/init.d/wpa_wifi.sh I have:

#!/bin/sh
# wifi wpa_supplicant init
echo "* [Wifi] enabling wpa_supplicant..."
if [ -x /sbin/wpa_supplicant ]; then
        /sbin/wpa_supplicant -B -c/etc/wpa_supplicant.conf -iath0 -Dmadwifi -w
fi

I used the following to get that shell script to run on boot (not the
official way, I don't think):
sudo chmod +x /etc/init.d/wpa_wifi.sh
sudo ln -s /etc/init.d/wpa_wifi.sh /etc/rcS.d/S40netwifiwpa

And my /etc/network/interfaces for the ath0 looks like this:

auto ath0
iface ath0 inet dhcp

Most of this I got from http://doc.gwos.org/index.php/Ipw2200_wpa and
adapted for atheros. Hope that helps. Good luck!
