Package: kernel
Version: 2.6.8-powerpc
This kernel does not provide sound for the new Mac Mini. Others have
worked out a partial fix, and various lists give the following
suggestions.
The first possibility is:

chip->control_mask = MASK_IEPC | 0x11; /* disable IEE */
}
This prospect has the disadvantage that the system hangs for a few
moments from time to time. Very noticeable at boot; one might first
think the system has frozen altogether.

This prospect doesn't cause the system to hang.
I have to make a few disclaimers:
1. I tried this change on the 2.6.11.3 kernel. I don't know about
2.6.8. It worked for me on 2.6.11.3 with this change.
2. I am not a kernel or device driver developer, and I do NOT know what
I am doing. I am making an obvious and huge mistake, please bear with
me.
3. I don't know if the proposed change would break other hardware which
works; e.g. other Mac and PowerPC products.
4. I don't know if this bug would be important for Sarge rc2.
Thank you very much for all of your effort!
