Maybe someone on linuxppc-dev can quickly check? Does a G5 use
I2C_POWERMAC for access to the codecs? I think it does, but there are
other I2C busses as well.

I'm not sure how much we should force the users to a sensible
configuration ;) But I suppose selecting I2C_POWERMAC is fine for all
relevant machines for now.

Agreed.
A relevant question: do we need I2C_POWERMAC for both onyx and tas?

Yes, there are PowerBooks and G5s with either. Actually, a bit more
thinking about this I'm pretty sure that it is used on all G5s by way of
how things are hooked up. There are SMU I2C busses too but they surely
don't connect any sound i2c stuff.

OK, now I added both I2C and I2C_POWERMAC and committed to ALSA tree.
