WLAN driver broadcom43xx links now. Needs to be tested as I don't own the

required hardware (many current Macbooks). 
This driver needs a firmware. The retrieval of this firmware requires 
following steps:
 a) Download the linux firmware from http://downloads.openwrt.org/sources/wl_apsta-3.130.20.0.o
 b) Download and compile b43-fwcutter from http://bu3sch.de/b43/fwcutter/b43-fwcutter-011.tar.bz2
 c) Use b43-fwcutter to cut the linux firmware in pieces.
 d) Copy those pieces into /system/data/firmware/broadcom43xx/
 e) Prepend them with bwi_v3_ and remove the .fw ending.
 f) You also need to create an empty file called bwi_v3_ucode in this directory.
