How to enable broadcom wireless with Net Install (Opensuse 12.1)

Hi everyone!
I want to install Opensuse with the Net Install method, but I haven’t the possibility to connect with the ethernet cable.
Opensuse don’t recognize my wireless device, so I have read in the advanced settings that there is the possibility to load a driver for a specific device.
Now, how can I load the driver for my wireless card?
The wireless card in question is a Broadcom bcm4313.
I have tried both the b43 and b43-legacy driver, without success.
Thank you for your time!

Search in packman repo and try looking for broadcom-wl and broadcom-wl-kmp-desktop, hope that helps
