unable to put wireless card in monitor mode

hi,

I am running Ubuntu 9.10. on Acer Aspire One with following card:

Ethernet controller: Atheros Communications Inc. AR5001 Wireless Network
Adapter (rev 01)

I have madwifi installed. I am trying to put the wlan0 interface to monitor
mode. For that I wanted to issue the following commands:

sudo wlanconfig wlan0 destroy
sudo wlanconfig create wlan1 wlandev wifi0 wlanmode monitor
sudo wlan<x> up

But, my first try resulted in

laptop:~$ sudo wlanconfig wlan0 destroy
wlanconfig: ioctl: Operation not supported

Please suggest me necessary steps to put card in monitor mode.

Thanks in advance
uv.
