What i have for i2s is:

[maybe the superfluous information could be interesting: i don't have the
cpu-frequency stuff, and it looks like i can't boot the kernel with the
frequency scaling patch, it alfays fails with a "decrementer exception", or=
 an
invalid memory access]

so for i2s:

not very interesting, but i have these i2s-a and i2s-b:

This one is probably the internal modem

I hope this information can help, it would be great to get the sound workin=
g on
this machine.

Do not hesitate if you want more information from openfirmware, or want me =
to
test patches.
