There is also firmware difference : b43 need v4 and b43legacy need v3. But v4 firmware seems to support core 4 (pcm4 & ucode4) and b43 code got some support for old chips (<5). Is the split was made because nobody know how to use firmware v4 with core 4 or because core 4 it so different from newer core. In the latter case why code for older chip (<5) is not removed from the driver ? Thanks Matthieu PS : sorry if the answer is already available on internet, I try to search it without finding anything.
