building kernel for ac97 sound card

[Linux for blind general discussion]

Here:

didier[~]$ zgrep -i ac97 /proc/config.gz  
CONFIG_SND_AC97_CODEC=m
CONFIG_SND_AC97_POWER_SAVE=y
CONFIG_SND_AC97_POWER_SAVE_DEFAULT=0
CONFIG_SND_SOC_AC97_BUS=y
CONFIG_SND_SOC_AC97_CODEC=m
CONFIG_AC97_BUS=m

Unless you are building a custom kernel I am a bit surprised:
as far as I know pretty much all distributions ship kernels
with ac97 provided as modules.
