First off. Welcome to LQ.
You are going to need to use ndiswrapper to get your card working.
Here is the closest thing I have to help.
RedHat site
Search google for ndiswrapper and your wireless card/distro.
I'll keep looking if I see anything else I will post back here.
Wish I could be more help.
Hopefully this will at least point you in the right direction.
Good Luck
Regards,
Blair
