Thank you very much for this information!

Enclosed is Darwin's source for the audio and the I2C controller.

You'll notice that they have 2 copies of the I2C code (one in the
audio driver itself and one separate). A quick look shows they are
identical (or very similar), but you should diff them to be sure.

Darwin is GPL, isn't it? So I can copy and modify the code for linux-kernel?

whatever free time is left to me).

No you can't. Darwin is using a different licence that is not compatible
with the GPL. You can "use" the Apple code as a reference to how the
hardware works, but you can't re-use it "as is".

Ok. Understood. I vaguely remember RMStallman warning of the apple source
license.
Another time to reimplement the wheel.

Here is a port of the unofficial hack to 2.4. It works well for me (booting via
OF without Apple OS).
Volume setting still needs to be resolved. I'll try it via linux' IIC layer.
