I am using pci-stub, blacklisting radeon and even passing these cards correctly to my VMs (3 radeons total). But it always complains about ROM, even in dmesg when I start my VMs. Somehow, it doesn't seem to affect their performance. This is why I wonder whether passing these cards as secondary adapters to OVFM VMs would even require UEFI bios.

I tried that link several months ago but I am getting "Invalid Rom Content" when trying to get the ROM file.

Make sure you're using pci-stub, blacklisting radeon, or otherwise booting the card in a pristine state.
