System.map says: 80488e60 D ac97_bus_type
Fwiw, I'd start by looking at soc_ac97_dev_register()
Do I need call a special ASoC function to create an AC97 bus, like the snd_soc_new_ac97_codec() function, from board code?
ac97_bus_type is declared in ac97_bus.c, so there is no function to create it. The generic AC97 driver (codecs/ac97.c) does all the ac97 init for you in ac97_soc_probe (e.g. create PCM's, register with AC97 bus, create new AC97 mixer, register card), although I've never turned on the list debug here.
Btw, is there anyway you can post your code ? It should make debugging a little easier and I can host it on my dev branch.
