Henry, I've made quick simple comparison of wl (which is slightly newer version of brcmsmac) with b43 for my 14e4:4329 card. I chose this card, because it's affected by DMA hardware bug we've recently added fix for in ssb&b43. You can see attached files for raw results or view chart at my blog: http://zajec.net/blog/view/2011-b43-dma-fixed-on-some-pci-cards As you can see, b43 is very comparable with wl/brcmsmac and sometimes can achieve even higher speeds (for high rates in this case). I believe this will make you calmer about quality of the b43. -- Rafał
