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:
