Well m8s,
Finally after few hours of googling, I find out the official support of the
http://www.madwifi.org/ and especially
http://madwifi.org/wiki/UserDocs/Distro/Debian/MadWifi where I found perfect manual for installing the card.
Just follow the instructions carefully and I think that on Debian etch 4.0R1 will work just well.
10x 2Gnu for the helpful post.
Here is config details of the card:
