Acer Extensa 5520 wireless problem under linux

This laptop has a Broadcom 4311 wireless adapter and it doesn’t work under openSUSE. An ifconfig eth1 up shows

SIOCSIFFLAGS: No such file or directory

It turns out that we must patch the firmware although the bcm43xx driver is included in kernel 2.6.22:

wget http://downloads.openwrt.org/sources/wl_apsta-3.130.20.0.o
wget http://linuxwireless.org/download/bcm43xx/fwcutter/bcm43xx-fwcutter.tar.bz2
tar -xzf bcm43xx-fwcutter.tar.bz2
bcm43xx-fwcutter/bcm43xx-fwcutter -w /lib/firmware wl_apsta -3.130.20.0.o

Reboot, and voila … there is wireless
