--- Comment #19 from [email protected] ---
that last one patch also works for me, even if I only tested it with drm-612
(installing nvidia-drm-kmod on 15.1 from ports, latest, pulls 6.12 drm packages
it seems).

While testing, i also put a couple of printfs in vt_drmfb_init
(drivers/gpu/drm/vt_drmfb.c) and drm_fb_helper_init
(drivers/gpu/drm/drm_fb_helper.c): these functions do not get called when
loading nvidia-drm.

Apparently when the glue for making VT console switching work with drm was
written in 2023 by dumbell, (https://github.com/freebsd/drm-kmod/pull/243), it
was not known if the nvidia-driver used/exposed drm:
https://github.com/freebsd/drm-kmod/pull/243#issuecomment-1723030095

I'd put it in a new bug, but I don't know which component to assign it to
(drm-kmod or nvidia-drm?)
