I have a T43 with Atheros AR5212. RC7 sees this on install and installs
the genmac atheros ar5211 driver.
GA 2.0 does not see the card on install. :-(
After sorting that lot out I start XWlan. Setting WPA2-PSK results in a
string of errors in the wpa supplicant window. Luckily my router is in
WPA compat mode so switching to WPA-PSK gets a connection.
Under Ubuntu the card works flawlessly to WPA2-PSK. Well it would :-)
