With all due respect to the effort.. Projects built around unsupported ways to use someone else's products, aren't they doomed from the very start? This race that you can't win isn't it a recipe for imminent burnout? I don't even mean that Apple has no interest in this project in the best case, but why Linux maintainers would want to accept changes that are necessary to support such a marginal use case?
Stuff like this is fairly common. Drivers for the Wiimote and other Nintendo controllers were not put in the kernel by Nintendo employees or with their blessing. Sometimes you want something to work and the only way is to handle it yourself.
