Either one or a combination of commits 3a3dd0186f619b74e61e6f29dddcaf59af7d3cac "Improve detection of devices from device-tree" and 26b0d14106954ae46d2f4f7eec3481828a210f7d "Adapt to new i2c probing scheme" broke the snd-powermac module for my PowerBook6,5 machine (12" iBook late 2004). As I understand things, these machines should be moving over to use snd-aoa.
The attached patch (against a 3.13.0 kernel) creates a new snd-aoa layout entry for PowerBook6,5 machines. I've tested it on my iBook and sound now appears to be fully working. The module snd-aoa-i2sbus needs to be added to /etc/modules to ensure all the necessary snd-aoa modules are loaded.
