Make sure you have pcmciautils.tazpkg installed.
#modprobe pcmcia
#pccardctl info
#pccardctl insert
Check dmesg for helpful info after you run these commands.
If you still get no info on the card:
Look in the Armada bio's for setting's related to the cardbus,try different options.
Either the cardbus or the wireless card could be the problem unless you know the wifi card works in another computer.
This thread on the old forum is related,it may be of some help:
