Did you run b43-fwcutter to extract the firmware?

Do you have files in directory /lib/firmware/b43/?

I use the openSUSE distro, which includes a script 
/usr/sbin/install_bcm43xx_firmware that downloads the necessary Broadcom driver 
file, extracts the firmware using fwcutter, and writes the files to the firmware 
directory. I have no idea how PCLinuxOS does it.
