fedora化したノートPCのwireless lan有効化めも

初期状態だとwlanを有効化にしても「ファームウェア無し」と出てしまう。

うちの環境
Broadcom 4311BG WiFi Adapter（802.11b/g）

# uname -r
3.1.4-1.fc16.x86_64

ファームウェアの切り出し？に使うツール
b43-fwcutter-014-1.fc15.x86_64

使えるfirmwareのイメージは -l で確認
# b43-fwcutter -l
b43-fwcutter version 014

Extracting firmware is possible from these binary driver files.
The column shows the unique identifier string for your firmware.
You must select the firmware with the same ID as printed by the kernel driver on modprobe.
Note that only recent drivers print such a message on modprobe.
