  ...but they were close; it seems the primary limitations are: 1. The inscrutable nature of the Nvidia proprietary drivers (which wouldn't compile on ARM32, and had an initialization error with no extra helpful output on ARM64). 2. The lack of IO BAR address space on the BCM2711 (SoC) used in the CM4/Pi 4.
