I was having a terrible time getting the Broadcom 4328 chipset working under 11.2, I however got it working by using the install_bcm43xx_driver and then searching for broadcom on software.opensuse.org/search until i found the broadcom-sta driver. I did not want to use ndiswrapper, i consider this cheating… 
After installing this and rebooting, my wifi light blinked on and i connected to my router.
Also found this great 1 click to get my Nvidia card working with
the desktop effects: NVIDIA - openSUSE.
I need help however, turning off the awful PC speaker beep when opensuse shuts down. Can someone point me in the right direction there?
