> It seems like you are not using SeaBIOS. Normally, Seabios initializes PCI devices. Are you sure you are using the same coreboot configuration that worked fine for your GTX660 with this ATI card or did you rebuild/reflash coreboot inbetween?
If you don't use SeaBIOS you need to enable PCI-e Option ROM/VGA ROM
