Script postinst of package firmware-b43-installer is modified to load the classic firmware for broadcom-cards,
according to note at https://wiki.archlinux.org/index.php/Broadcom_wireless#b43
Logic is added to also load the correct version, in case the
firmware is unconditionally loaded.
New postinst and diff are attached, I hope.
I did not properly indent the postinst-file!
