With respect, thats not really true, because I've just rebooted my Etch
install to the 2.4.27-2-386 kernel and Alsa works with no problems.
Personally I liked the 2.4 kernel, as it has a separate
Alsa-modules-2.4.27-2-386 package, and the Alsa driver was updated more often
than the Alsa driver that came with the 2.6 kernel.

Agreed. The Alsa stuff I have installed is, Alsa-base, Alsa-oss, Alsa-utils,
and obviously for the 2.4 .27 kernel, the Alsa-modules-2.4.27-2-386 package.

If Alsaconf picks up your card ok you can see if it's truly there by running.
cat /proc/asound/cards
Running. cat /proc/asound/version will show you the Alsa driver version.
Alsamixer is often initially muted when a card is first setup, so open
alsamixer on the CLI as user. Your card appears to be supported, but I don't
know what controls you will see on your alsamixer. Mine for the Audigy2
soundblaster shows "Master", "PCM", and "Front", as the main sliders to get
some sound out. Also look on alsamixer for controls that are muted. The "M"
key toggles the mute/unmute.
Apologies for poking my nose in on this thread.

btw:
I can't say it went so easy for me, perhaps because I've also got a usb midi
keyboard, and usb on bootup starts early, and messes with the soundcard
loading. Alsa was seeing my keyboard as a soundcard, and setting it as card0,
and consequently the real soundcard was set as card1, resulting in no sound.
It meant setting some index options for the soundcard (snd-emu10k1), and for
the usb midi keyboard using (snd-usb-audio).
