The following couple steps allowed me to get my BSM43XX wireless internet card to work in my Presrio V5000 laptop, running Ubuntu Hardy Heron 8.10. I found the steps at the Ubuntu Forums.

Do the steps one line at a time.

sudo apt-get install build-essential

wget http://bu3sch.de/b43/fwcutter/b43-fwcutter-011.tar.bz2

tar xjf b43-fwcutter-011.tar.bz2

cd b43-fwcutter-011

make

cd

export FIRMWARE_INSTALL_DIR=”/lib/firmware”

wget http://downloads.openwrt.org/sources/broadcom-wl-4.80.53.0.tar.bz2

tar xjf broadcom-wl-4.80.53.0.tar.bz2

cd broadcom-wl-4.80.53.0/kmod

sudo ../../b43-fwcutter-011/b43-fwcutter -w /lib/firmware wl_apsta.o

Then restart your computer, and it should work fine. You might have to put in your wireless network password.
