Thanks guys, that helped me out and I solved it. The recipe was:

Get the driver from http://www.broadcom.com/support/802.11/linux_sta.php
For 32 bit: hybrid-portsrc.tar.gz
For 64 bit: hybrid-portsrc-x86_64.tar.gz

Setup dir and untar:
# mkdir hybrid_wl
# cd hybrid_wl
# tar xzf <path>/hybrid-portsrc.tar or <path>/hybrid-portsrc-x86_64.tar.gz

Patch the driver, download this patch: bc_wl_abiupdate.patch
# patch -p0 src/wl/sys/wl_linux.c < bc_wl_abiupdate.patch
# sudo make
# sudo make install
# sudo depmod
# sudo modprobe wl

Give the driver a little time to scan wireless networks, connect to your network, key in the password and your done.

Thanks and best regards,
Oliver.
