The "Nova" driver for NVIDIA chipsets

AMD has out-of-tree kernel drivers, but I bought nVidia because CUDA Just Works™ on consumer-grade cards with the tooling I want to use, I've only ever needed to upgrade off the Canonical-picked nVidia drivers three times in the last 20 years (one time because the GTX750 was too new for them), and I *CAN* upgrade off the Canonical-picked drivers without upgrading my whole kernel.

By contrast, when I reinstalled my mother's laptop with onboard AMD graphics, I had to switch her from the HWE kernel (6.5.x) to the regular generic kernel (5.x) because the AMD drivers were failing with UBSAN errors in the kernel log.
