It doesn't look like a hardware problem : I tried with four different cards in the two pcmcia slots of the laptop and the problem is exactly the same.
A dmesg after loading the module only returns : ath_hal: (AR5210, AR5211, AR5212, RF5111, RF5112, RF2413).

That's what you would see if the hardware is not present or doesn't
function correctly.  See kernel messages using the "dmesg" command.
