I'd noticed that too, that the kernel (from 2.6.17 til 2.6.23) detected the on-board sound card even when it was set to "disabled" in the BIOS. I double checked the BIOS setting, and it is definitely enabled.
Before kernel 2.6.17 I couldn't get the two cards working simultaneously... hmm, I wonder if a "feature" (read bug!) that made my setup work has been fixed!
Can the on-board be disabled by the presence of another sound card (over-riding the BIOS setting)?

Does anyone have any suggestions as to why this may have stopped working in moving from 2.6.23 to 2.6.24? Is it no longer possible to run two sound cards together?
I got the same problem with my (only) built-in VIA sound chip. From kernel 2.6.24 and onwards, the chip has to be enabled in the bios. I had it disabled before. Check your bios settings, and enable the card if it is disabled.
Before linux ignored bios settings, but it look likes it does not do that anymore.
