As the b43-fwcutter version is correct (011)

To make the b43 driver running you need to do

export FIRMWARE_INSTALL_DIR="/lib/firmware" # or /lib/firmware/$kernel_version

(i have actually done it on both paths, don't know where it should really go)

wget http://downloads.openwrt.org/sources/broadcom-wl-4.80.53.0.tar.bz2 # <<< the correct tarball !!!
tar xjf broadcom-wl-4.80.53.0.tar.bz2
cd broadcom-wl-4.80.53.0/kmod

# as the b43-fwcutter package is installed, this
b43-fwcutter-011/b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" wl_apsta.o

I have an Acer 3023WLMi and from the previous Gutsy installation, it has the acer-acpi package.
I do it in recovery mode, and when leaving it, going into normal X session, the card just starts working normally.

(in recovery mode, because I need to fix the sudo, but that is a topic for different bug actually...)
