I hope so, too :)

I have the same b4312 dma errors.

$ dmesg | tail -7
 Registered led device: b43-phy0::rx
 Registered led device: b43-phy0::radio
 __ratelimit: 8 callbacks suppressed
 b43-phy0 ERROR: Fatal DMA error: 0x00000400, 0x00000000, 0x00000000, 0x00000000, 0x00000000, 0x00000000
 b43-phy0: Controller RESET (DMA error) ...
 b43-phy0: Controller restarted
 b43-phy0: Controller restarted

I built b43 from daily tarball compat-wireless-2009-09-07,tar.bz2 .

Card: B4312 low-power phy, 
BCM4312 802.11b/g [14e4:4315] (rev 01) (on a Dell Mini 10, N-Series). 

Kernel: 2.6.31-rc9 . 32bit. 
Hyperthreading Patch: I assume this means
http://bu3sch.de/patches/wireless-testing/20090816-1535/patches/002-b43-threaded-irq-handler.patch

I did not actually apply this patch, i just checked the source for a few
lines added in this patch and assumed it is merged in the daily tarball
already. Is this correct?

Firmware: Debian Sid. b43-fwcutter version 012 comes with 4.150 fw it
seems. On Openwrt I only found the afore mentioned "v478" firmware
http://downloads.openwrt.org/sources/broadcom-wl-4.178.10.4.tar.bz2 .
b43-fwcutter does not work with it. Is there documentation as to how
to extract newer firmware?

I couldn't find the v5xx firmware. It's nowhere on your sites, is it?

Let me know if there is something I can do to help, but be aware I am
not knowledgeable with linux-wireless, it's my first WLAN Device in
Years. And your site is a bit.. confused.. errm confusing ;)

Cheers,
 Markus
