It is a radeon but it's an older one that's not supported by DRMKMS.
(Before they were excluded in the code, they would exhibit almost-
black-on-black video in the framebuffer console, although X worked fine.)

For this (and some other) machine(s), the kernel configures the legacy
DRM driver (it would be nice if the legacy-supporting X driver could be
named differently so it wouldn't require a symlink dance after updating).

(The legacy DRM drivers have their own problems lately.  See:

  http://mail-index.NetBSD.org/current-users/2019/11/18/msg037067.html

for more.)

Linking gallium when building netbsd-9 (GCC 7) works.
