BCM43XX Wireless drivers

[Alexey Ivanov]

In my notebook i have

ndis0 at pci0:48:0:0:   class=0x028000 card=0x1371103c chip=0x431214e4 rev=0x02 hdr=0x00
    vendor     = 'Broadcom Corporation'
    device     = 'BCM4310 broadcom wireless 1490 (dell)'
    class      = network
    cap 01[40] = powerspec 3  supports D0 D1 D2 D3  current D0
    cap 09[58] = vendor (length 120)
    cap 05[e8] = MSI supports 1 message, 64 bit
    cap 10[d0] = PCI-Express 1 endpoint

and as i know it's currently not supported by FreeBSD. 
I've downloaded http://paradox.lissyara.su/bwi.01.tar.bz2 (it's sources from some p4 branch that is actually dragonflybsd bwi driver port) but still no luck, cause all modern broadcom cards need v4 firmware.
I also extracted/built v4_150 broadcom firmware (http://opticomspb.ru/~savetherbtz/freebsd/bwi/bwifw_v4_150.tar.bz2) and found site with it's cpecs http://bcm-v4.sipsolutions.net/ on which Linux driver is based

But with my knowledge of C i can't write driver =(
FreeBSD forums thread here http://forums.freebsd.org/showthread.php?t=170

Is there any work going that way? Or Broadcom Wi-fi will always be unsupported on FreBSD.
