[sf-lug] how to get wifi Javacat

hi

Jason Turner helped me get wifi working on my IBM Thinkpad at Java Cat via
Knoppix 5.x .  This is a really fantastic solution for me, because I had
been using a Netgear wifi card that I just had not been able to get working
under openSUSE 10.1, and I have not yet had time to install either 10.2 or
10.3.  My working wifi card had been stolen out of a rental car more than
one year ago, and though a series of bad circumstances I came into this
Netgear card, but have never been able to get it working for this notebook.
So in solving my Javacat problem, he has helped me solve the broader problem
as to how to get access to the Netgear card.

But his solution might work for John and maybe a few other folks who weren't
able to get on at Javacat.

Out of courtesy for javacat, I have deleted the password for Javacat.

Thanks again, Jason!
