kvm=off masks the KVM cpuid leaf, it does not disable the guest's ability to detect that it runs in a VM, only that it runs in a KVM VM.

You're passing a ROM file, which is often just as likely to cause problems as solve them if there's something subtly wrong with the image you're using. Guest driver issues can also be a result of the handling of the card in the host, for instance the device being used as primary graphics in the host or allowing host drivers other than vfio-pci or pci-stub to attach to the device.
