Well, quoting https://wiki.freebsd.org/Graphics about drm-kmod

Generally speaking if you have a system with one of these graphics
adapters it is suggested to install the drm-kmod metaport, which should
work well on systems starting with the "Broadwell" generation. This code
is under active development and allows us to track more closely the
drivers present in the Linux kernel.

"This code is under active development" does not sound like "old
drivers."

Well, I ran "pkg install graphics/drm-kmod" which resulted in the
following packages being installed:

# pkg info -dr graphics/drm-kmod
drm-kmod-g20190710
Depends on     :
        drm-fbsd12.0-kmod-4.16.g20191120

Yes! That's the point of my question.

I asked first!!! :-)

Indeed. That's why I started the thread.
