That's really old. If you're using any slightly recent ALSA version, the 
module for the AC97 codec is snd_ac97_codec. Also, you'll need a hardware 
specific module. I'd suggest you have a look at the driver-specific 
instructions for the ALSA modules:

http://www.alsa-project.org/alsa-doc/

Also, you'll want to grab the recent ALSA packages, depending on what kernel 
you're using.

2.4.x from debian package: Get the appropriate alsa-modules package.
2.4.x from source: Either get the alsa-source package or patch the kernel 
yourself from the stuff available at the ALSA site.
2.6.x comes with ALSA as default sound infrastructure. Consider upgrading your 
kernel.

An example lsmod output from my box with 2.6.10 kernel (irrelevant parts cut):
