iommu is a requirement for PCI assignment, any partial support for iommu-less operation has been disabled as it never worked upstream and presented a security hole. Google guesses this is a PCI device, so you'll need a system with VT-d or AMD-Vi (if it's indeed a legacy PCI device vs a PCI-e device, it's often easier to make those work on VT-d).
