I had no problem with BT3 but now the BT4 prefinal cannot recognize these two cards, the first is in the laptop Toshiba M40 and the second a pcmcia attached. I have dual booting with WinXP and Ubuntu 9.04 on the same laptop and these cards work just fine, so its definetely some problem with BT4.
Any help to solve this, very welcome!!!

here is the output of dhcpcd with one card (wlan0):

sudo dhcpcd wlan0
err, wlan0: timed out
warn, wlan0: using IPV4LL address
dhcpcd.sh: interface wlan0 has been configured with new IP=
