card has something special : it's not a native PCI-E sound card, but a native 
PCI one, so it uses the "PCI bridge: PLX Technology, Inc. PEX8112 x1 Lane PCI 
Express-to-PCI Bridge (rev aa)" as a bridge to communicate with the 
motherboard. And THIS component isn't supported!

No, that wouldn't matter.  Bridges are fairly standard.  It would be helpful 
to get pciconf -l output so we could see the actual device and vendor ID 
register values.
