Unfortunately, drm-515-kmod and FreeBSD-14 don't quite work properly. You may
be able to get the graphics to work, though not well, by deleting the firmware
so that it is not loaded. You can simply delete the gpu-firmware port from the
system. That will leave you with working graphics, but no acceleration. The
only real solution is to run CURRENT and drm-61-kmod, which is what I do. It
provides fully functional graphics on the Alder Lake GPU.

I have no idea whether a minor 14 release will support drm-61-kmod. It seems a
bit unlikely as it would require an update to the LKPI to 6.1 and that usually
means that it will require a major version update.
