No. You need the ac97 module, but you also need the module for your
sound chip, which is probably snd_i8x0 (if you use ALSA) or i810_audio,
if you use OSS. The ac97_codec is an OSS driver, if you want to use
ALSA instead, you need the ALSA modules that replaces it.

This means that the driver is not present. Make sure it gets loaded. Try

You can use ALSA, but you must make sure that the ALSA modules for your
kernel are installed as well as the ALSA userspace packages. You need
alsa-modules-2.4.26-1-386, alsa-base, alsa-oss and you probably also
want alsa-utils. Please make sure that these packages are installed in
the latest versions. If hotplug and discover1 are installed, also
upgrade them to the latest versions. Otherwise you will get conflicts
with the OSS drivers. It is possible that the modules for your kernel
(as well as the kernel itself) are no longer available in Sarge and
Sid. In that case upgrade to 2.4.27 or 2.6.

As I wrote above, these modules are not sufficient.
