As I said, I'm running a Dell OptiPlex GX260 wiht the intel 845G/GL chipset. Here's what I have sound wise for modules (kernel 2.4.20)

i810_audio 20200 1
ac97_codec 9736 0 [i810_audio]
soundcore 3268 2 [i810_audio]

BTW - if you have the 845 video, you need X from CVS to make it work properly. Drop me a PM with questions.
