2.6, modules, and ALSA

[Peter Sebastian Masny <ps-list@masny.dk>]

Hi, I'm using kernel-image-2.6.2-1-k7.
I have included "snd-via82xx" in my /etc/modules and run update-modules 
(modules-init-tools installed).

My dmseg says:
> via82xx: Assuming DXS channels with 48k fixed sample rate.
>          Please try dxs_support=1 option and report if it works on your machine.
> PCI: Setting latency timer of device 0000:00:11.5 to 64

but my lsmod has:

> snd_seq                55312  1 snd_seq_midi_event

Notice that sound is used by via82cxxx_audio (which is not mentioned in 
dmesg).

to my understanding, via82cxxx_audio and ac97_codec are OSS, while 
snd_via82xx and snd_ac97_codec are ALSA.

My question is, how do I force the kernel to use the ALSA drivers and 
not load the OSS ones?

Thanks in advance,
Peter
