  7	  b43 is a driver for the Broadcom 43xx series wireless devices.
  8
  9	  Check "lspci" for something like
 10	  "Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller"
 11	  to determine whether you own such a device.
 12
 13	  This driver supports the new BCM43xx IEEE 802.11G devices, but not
 14	  the old IEEE 802.11B devices. Old devices are supported by
 15	  the b43legacy driver.
 16	  Note that this has nothing to do with the standard that your AccessPoint
 17	  supports (A, B, G or a combination).
 18	  IEEE 802.11G devices can talk to IEEE 802.11B AccessPoints.
 19
 20	  It is safe to include both b43 and b43legacy as the underlying glue
 21	  layer will automatically load the correct version for your device.
 22
 23	  This driver uses V4 firmware, which must be installed separately using
 24	  b43-fwcutter.
 25
 26	  This driver can be built as a module (recommended) that will be called "b43".
 27	  If unsure, say M.

 62	  Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA
 63	  devices, but 32bit CardBUS devices. CardBUS devices are supported
 64	  out of the box by b43.
 65
 66	  With this config option you can drive b43 cards in
