the important things are generic iee support, software mac add-on
then go to
device drivers - network device support - wireless lan
and there you should find these options:

 <M> Broadcom BCM43xx wireless
support

  � �                                     [*]   Broadcom BCM43xx debugging
(RECOMMENDED)                                                              �

  � �                                           BCM43xx data transfer mode
(DMA + PIO)  --->

you cannot see them before setting to module or compile into kernel of the
softmac addon.
this should be your default settings. then recompile and install the kernel,
install the bcm43xx-fwcutter from the gentoo repository and run it to cut
the file i've appended. then copy all the .fw in the /lib/firmware directory
and reboot.

if you have installed the sabayon overlay you have the bcm43xx-firware
packet that has the firware already cut and you just need to install that
package. for having the better experience of bcm43xx use the latest kernel
source cause the guys of bcm43xx project get fixes and new supports for
these drivers.
it should take about 5min to install everything and reboot.
