+===== Linux Broadcom b43/b43legacy driver Frequently Asked Questions =====
+==== Q: The LEDs do not work. ====
+A: You have to enable LEDs support in the kernel configuration. The config options you have to enable are: CONFIG_LEDS_CLASS, CONFIG_LEDS_TRIGGERS, CONFIG_MAC80211_LEDS.
+==== Q: The radio-enable-button on my laptop does not work. ====
+A: You have to enable RF-kill support in the kernel configuration. The config options you have to enable are: CONFIG_RFKILL, CONFIG_RFKILL_INPUT, CONFIG_INPUT_POLLDEV.
+==== Q: After enabling the config options, LEDs/RF-kill still don't work. ====
+A: If you have the b43/b43legacy driver built-in (not as a module), you must also enable all the LEDs/RF-kill options (see above) built-in (not as a module).
+==== Q: I'm confused about this b43/b43legacy business. Which one do I need? ====
+A: If your chipset is 802.11b-only or BCM4306 rev 2, you need to use b43legacy. All other devices, including BCM4306 rev 3, use b43.
+You can also ignore this issue and simply compile both drivers, they will automatically detect which one you need by themselves and the appropriate one will be loaded.
