NEWBIE QUESTION: udev and a "AC97" sound device

I suppose this is a bit of a complaint about the available documentation on udev. At least on my Ubuntu installation, I can't find much (README, Release-Notes, FAQ). My MSI/nVidia box contains an AC97 sound card. Some Googling turned up a usenet posting advising another unfortunate to:
"Recreate the correct device files with mknod. Use the following major and minor numbers:

14,   3   /dev/dsp
14,  19   /dev/dsp1
14,  35   /dev/dsp2
14,  51   /dev/dsp3

The error message you get is a bit misleading. What it means is: the driver module is not loaded"

But, of course, my distro has udev. I'll venture a SWAG that the equivalent involves something like 'NUMBER, . . . NAME="dsp"' but I'm a bit chicken about messing with the /dev system.

If someone wants to say "Why didn't you look at . . ." (assuming I have a copy of ...), fine. I know a whole lot about computers and programming, but not yet nearly enough about linux.

Anyway, TIA

These are OSS nodes.
Have you tried:

$> modprobe snd_mixer_oss
$> modprobe snd_pcm_oss
