I don't know why the audio card is not listed, but the nvidia is sharing an IRQ
with other hardware. I was having big troubles (the system was freezing to
death sometime) with it until I solve this. I found 2 ways to do that in my box:
1) use the nv 2D driver so the nvidia card will not use an IRQ (but it will be
only slow software 3D).
2) disable acpi so at acpi don't use any IRQ. (I use this IRQ for the
sound card)
