Hello world!

I'm trying to run Gentoo on a new Macbook Proc 13" and I get troubles to get the wireless card recognized.

I followed this docs:

But the card don't care about the module...

    kopf ~ # modprobe b43
    kopf ~ # lspci -vnn -d 14e4:4331 -k
    02:00.0 Network controller [0280]: Broadcom Corporation BCM4331 802.11a/b/g/n [14e4:4331] (rev 02)

I use Genkernel, here the last config generated:

I'm that it can work, but I don't found what I have missed, if someone have an idea :)

I don't have your NIC, but as I read the info available it is not 80211n capable and uses ssb bus not bcma and uses the ht-phy not N or lp.

If you follow this but still no luck check dmesg for clues.
Defund the FCC.
