Although the driver is present, SUSE needs the Belkin firmware which is not included in the distro for I suppose legal reasons. See http://bcm43xx.berlios.de/
for the fw_cutter. You have to extract the firmware from Win drivers so that it can be copied to the wireless card. With firmware copied to the appropriate directory, things should work. You can think of the firmware as your card's embedded operating system.
You should be able to easily research the bcm43xx issue. You have a choice to use the native driver plus firmware, or just use ndiswrapper with your Windows .inf and .sys files.
In an earlier post, 2Gnu recommended the ndiswrapper method as superior. I tried it after using the native driver, and agree that ndiswrapper works better with this chipset [thanks, 2Gnu]. Much faster and better connection. Check the earlier posts on this topic. If you go with ndiswrapper, you need to blacklist the bcm43xx driver and boot clean to install the ndiswrapper. Or if you don't mind the slower speed and prefer the native driver, you need to generate the .o file with the firmware cutter. There are quite a few posts on the bcm43xx issue.
