Wifi Driver for Inspiron 1564?

Hello, sorry to dredge up the past, i know this is an old problem but i cant find an answer younger than 2005.

Running:-
/sbin/lspci -vnn | grep 14e4

I get:-
03:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)

i've seen a workaround for centos:-
yum install b43-fwcutter b43-openfwwf
mkdir ~/b43-driver; cd ~/b43-driver
wget http://downloads.openwrt.org/sources...0.10.5.tar.bz2
tar jxf broadcom-wl-4.150.10.5.tar.bz2
cd broadcom-wl-4.150.10.5/driver
b43-fwcutter -w /lib/firmware/ wl_apsta_mimo.o

before i try this though i thought i'd just ask if there was a more modern or better way to do it.

Thanks in advance :)
