If you pull the wireless-testing git tree, it is working, perhaps with minor
changes. See a recent mail message:

========================================
Awesome guys,
thanks for the pointers, it worked! (i m sending this email using the b43 driver!)

I used the wireless-next git, and then additionally applied the "b43: HT-PHY:
allow writing longer tables with a single call" patch.
(and the ones in Rafal's last mail)

Thanks for the great support and fast answers!
Congratulations on hacking a driver like this together, I am impressed!

Best regards,
Maxime

I'm going to clean HT-PHY (BCM4331) support in about a week, as David
wrote, it should be quite stable.

Most of the patches are already in wireless-next, I just need to test
that tree, see if everything was sent&applied correctly and drop
BROKEN from B43_PHY_HT.

If you're "brave" enough, you can:
1) Edit Kconfig and drop BROKEN from B43_PHY_HT
2) Edit dma.h and define B43_DMA_RINGMEMSIZE to "2 * PAGE_SIZE"
(or just wait a week).
