I’ve been there before with Gentoo, as a developer, but times and situations have changed. Over the years I’ve been deeply involved with Ubuntu for my work and at its heart, Debian. I’ve become a Debian Developer to help get closer to the development process, package management and maintenance to do my share of the heavy lifting.
The first thing I did was sign up at Alioth, a software ‘forge’ used by Debian for collaboration. Create a ‘New Account’ and just be aware that whatever login name you use, it will be appended with ‘-guest’. This will go away once you’ve officially joined Debian. At this point, it is also a good idea join a Debian mailing list and/or join IRC at irc.debian.org and have a nice chat with the folks in #Debian or their various sub-channels where you would like to help. It is important to have a sponsor/mentor that can help you out if you a problem. You will need them when getting accepted into the Debian community in order to start working.
The hybrid driver from Broadcom was updated again in September (2013) with all the previous patches and a few other fixes as well. This brings them up to support linux kernel 3.9, which is very much welcome.
Sadly it breaks again with >= 3.10 with many warnings and errors which isn’t good considering that Ubuntu (13.10) Saucy Salamander is about to be released.
We do have a patch for you though that gets us working again up to the 3.11 kernel.
Chipsets supported by “Broadcom’s IEEE 802.11a/b/g/n hybrid Linux® device driver” are: BCM4311, BCM4312, BCM4313, BCM4321, BCM4322, BCM43224, BCM43225, BCM43227 and BCM43228.
