Very easy, I used the ALSA driver in the 2.6 kernels. The following command modprobe snd_intel8x0; modprobe snd_mixer_oss; modprobe snd_pcm_oss should be all you need. You might also want to install the Debian ALSA packages such as alsa-base which does some nice things for you like make sure that hotplug doesn't load oss drivers for the card. If you want to use the volume up/down/mute buttons, see the keyboard section.
