I don't think this is a real problem. The reason one currently needs to
manually load the drm-next drm.ko (rather than just kldloading a driver
and having it pick up the right drm.ko automatically) is that our drm.ko
defines the same module ("drmn") as drm2.ko in the base system. So upon
attempting to load a drm-next driver, the kernel uses the linker hints
to load drm2.ko, which is incorrect. However, this can be addressed by
simply bumping the drmn version in the port and modifying the drivers
accordingly. I've submitted a 4-line PR which does exactly that. After
that change, we can modify the pkg-message to omit drm.ko from the
kld_list value. As a result, the name of our DRM module doesn't matter
since users don't need to specify it, so the collision with drm1 isn't a

With the PR I mentioned above, I think it's a non-issue to keep drm1 in
the base system. Since there appear to be at least some users of those
drivers, I really think it would be preferable to avoid removing them
unless it's absolutely necessary.
