I also have a broadcom wireless card in my notebook, You should use ndiswrapper & your winXP driver. If you need more information about ndiswrapper, look at homepage -> ndiswrapper.sourceforge.org. The best way to get it, is download sources and compile it. You also have installed kernel-sources, make & gcc packages.

 

If you have any problems, write here & also You can check suse forum.

 

Best regards.
