I think that this card is supported by the ndiswrapper driver. If so, since you have windows installed you can access the card's .sys and .inf driver files from your windows C:\WINDOWS directory.
This site's wiki has instructions on how to install and use ndiswrapper.
http://wiki.linuxquestions.org/
You need to install the ndiswrapper, wireless-tools and wpa_supplicant packages. Also the ndiswrapper-kmp package for the ndiswrapper.ko kernel module matching your kernel.
Also install the kernel-syms, and maybe the kernel-source package so that you will be able to modprobe the "ndiswrapper" kernel module.
The wiki explains how to do this. I would recommend downloading the ndiswrapper source, or the ndiswrapper source rpm. SuSE's current version didn't work for me. The modprobe step would fail, but uninstalling ndiswrapper, and installing from source using rpmbuild from the version 1.8 source worked.
