bwi(4) BCM4315 support?

Hi

I have the following card:

bwi0_at_pci0:1:0:0:        class=0x028000 card=0x1508103c chip=0x431514e4 rev=0x01 hdr=0x00
    vendor     = 'Broadcom Corporation'
    device     = 'Broadcom Wireless b/g (BCM4315/BCM22062000)'
    class      = network

By playing a little bit with the if_bwi source, I've managed to get
it detected to this point, but I obviously don't know what I'm
doing:

bwi0: <Broadcom BCM4315 802.11b/g Wireless Lan> mem 0xfeafc000-0xfeafffff irq 16 at device 0.0 on pci1
bwi0: [ITHREAD]
bwi0: BBP: id 0x4312, rev 0x1, pkg 0
bwi0: MAC: rev 15
bwi0: PHY: type 5, rev 1, ver 6
bwi0: RF: manu 0x17f, type 0x0002, rev 0
bwi0: only BCM2050 RF is supported for 11G PHY
device_attach: bwi0 attach returned 6

Is there any thing I can try?  Is there support on the horizon or
should I try and replace it with a supported card?

Ian
