I don't see where this message can come from.

It's not possible to compare the last code that was in sys/dev/drm2 with even
the first drm-kmod.
drm-kmod didn't originated from the sys/dev/drm2 code, it was started to be
port from scratch from the Linux code with Linuxkpi.
If radeonkms doesn't work for you on -CURRENT (I insist on -CURRENT as it's the
only branch activelly supported right now) please create a new issue at
https://github.com/freebsd/drm-kmod/. Note that it works for powerpc64 for some
devices and while it doesn't mean that it might work on i386 or with the
hardware that you have it means that it's not dead code.
I suggest you first try the image I've made a few weeks ago, see
https://lists.freebsd.org/pipermail/freebsd-current/2020-September/077024.html
for the links.

What brand/model is that ?
