Note1: The above was with compat-wireless-2008-07-19 driver.

Note2: AirCrack-ng does not have this problem, although it uses a different technique:

utumno:/home/leszek# iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

wmaster0 no wireless extensions.

wlan0 IEEE 802.11abgn ESSID:""

... and at this point I am able to use wlan0 in managed mode.

reading aircrack-ng wiki, they seem to say that in case of softmac mac80211 drivers like iwl4965, creating an extra 'mon0' device is the only correct way to put the card in monitor mode?
