Sound in linux? ASUS P5AD2, Fedora Core III

I have an ASUS P5AD2 premium motherboard with C-Media CMI 9880 sound built
into the motherboard. In the bios there are two options: AC'97 and HD
Audio

I'm running Fedora Core III, kernel 2.6.10-1.737_FC3smp.

Kudzu doesn't see the sound"card" when either option is set.

I'm wondering if anyone has been able to successfully get their sound
working from this motherboard? I suspect that I need some "drivers", but
a visit to the C-Media website doesn't identify any drivers for the 9880
series...

Suggestions? By the way, I would not recommend this motherboard if you
plan to use linux, its software is clearly made for Windows environments.

Thanks,

-Ben
