The graphics/drm-kmod port is a meta port that pulls in the correct
graphics/drm-<VERSION>-kmod port and all of the
graphics/gpu-firmware-<MANUFACTURER>-kmod@<CODENAME> ports. Just
rebuilding it will not rebuild the dependencies.

For FreeBSD-14 you need graphics/drm-515-kmod and one of the
flavors of graphics/gpu-firmware-intel-kmod to provide the firmware
files. Once graphics/drm-515-kmod is rebuilt load the i915kms kernel
module and then check dmesg for the name of which firmware file it
couldn't load. Most of the files are named something like alk where the
a stands for alder and the lk stand for lake. ```make -V FLAVORS```
in graphics/gpu-firmware-intel-kmod will give you all of the FLAVORS
you can build.

Once you know which flavor you need I would put the portmaster
incantation to rebuild graphics/drm-515-kmod and
graphics/gpu-firmware-intel-kmod@<FLAVOR> in a shell script that you
can run after every kernel installation.
