1) Please write to b43 ML for better support (you can use both lists)
2) Read http://wireless.kernel.org/en/users/Drivers/b43
3) From wiki: 2.6.38 has experimental support only, .39 is suggested
4) From wiki: BCM4321 sometimes does not work with DMA
5) To use pio: "rmmod b43; modprobe b43 pio=1"

I'm going to fix DMA errors on BCM4321, but I've some another things
to fix first. Observe b43 ML or wiki page for news.
