Dispositivos PCI Linux - não reivindicados

Question

MAC Pro de 15 polegadas SO: Gentoo

Gostaria de saber se alguém pode esclarecer como lidar com dispositivos PCI não reivindicados. Eu tenho a seguinte lista de dispositivos PCI não reclamados. Também tenho certeza de que incluí a configuração do kernel necessária para acomodar as informações abaixo.
