Urgh, sorry - ignore comment #5. The only reason I didn't see issues is that I hadn't yet installed nvidia-dkms in the guest :( Even with q35 I see the "NVRM: This PCI I/O region assigned to your NVIDIA device is invalid:" and following messages. Further, in q35 mode, pci=nocrs no longer seems to be a functioning workaround.
