What exactly prevents an old distribution from using new b43 given that they fix their broken udev scripts first?
(I cannot fix their broken scripts from within the kernel.)

Sorry if I didn't chose my wording correctly. But I was only talking about the development of drivers. It is correct that userspace ABI has to be preserved, but that is not an issue at all to drivers. I was talking about things like installing the right firmware for the new driver. It is the job of the distributors to install the new firmware when they introduce a new driver. It is the job of the distributors to test their userland scripts and configuration stuff with that driver and fix their stuff. It is _not_ my job to fix random distribution udev scripts or explaining over and over again to people how the firmware is installed. Either distributions have to install it automatically or people simply have to read one or two lines of documentation. That's just what I wanted to say.
Of course it is _my_ job to preserve ABI. I did never want to question that.
