Bug 260994 key phrase: Kernel Mode Setting.
<https://bsd-hardware.info/?probe=e2d694053a#pci:10de-0ff6-103c-2256> nvidia,
more specfically <https://bsd-hardware.info/?probe=e2d694053a&log=kldstat>
nvidia-modeset and <https://bsd-hardware.info/?probe=e2d694053a&log=pkglist>
x11/nvidia-driver-470.

x11/nvidia-driver-470 lacks what's required for nvidia-drm.
This HP ZBook 17 G2:

* failed to wake from sleep when I used the system console frame buffer
(an X.Org configuration) instead of nvidia-modeset (the kernel module).
The failure is consistent with <https://wiki.freebsd.org/Graphics#hardware>,
