The graphics/drm-kmod (installed) = "old drivers" at the
moment; graphics/drm-legacy-kmod will be "the new name"
for the "old drivers".

Very strange. You said you have drm-kmod installed, but
you get the "it's obsolete" message from something installed
by drm-fbsd12.0-kmod? Is that obsolete, too? ;-)

You should only need to install one out of those:

	(a) drm-fbsd12.0-kmod - for current drivers

	(b) drm-(legacy)-kmod - for "old drivers"

Note that I'm not sure in how far (a) can be used with
older _hardware_ i. e., if it will contain drivers that
will support it. I also don't know if the installation
location (!) does differ, or if something can overwrite
files...

If I understood the documentation correctly, drm-kmod
should not be used anymore, in favor of one of the two
options mentioned above.

The "new drivers" then. Again, that should not issue the
abandonware message initially discussed.



Very strange...
