Some tips:
0x24 is old G5's (PowerMac7,2 and 7,3) primary i2s bus
0x29 is not in my list so I don't know what machine it is
0x33 is aluminium powerbook 15" rev. 2 (PowerMac5,4)
0x3a is mac mini (I can test that one one of these days but we'll need
the
toonie codec, which is basically a "null" codec with only
the amps GPIOs available)
0x50 is not in my list
Also not in your list nor in the driver:
0x3c is recent single CPU desktop G5 (PowerMac9,1) (SMU based) bus
i2s-a
0x3d is same as above bus i2s-c
The later is a onyx + topaz setup iirc, possibly similar to the quad.
