--- Comment #15 from Ronald F. Guilmette <rfg-freebsd@tristatelogic.com> ---
In answer to the question regarding which driver I am using, I do not know =
how
to unambiguously determine the correct answer to this question, however I do
have a recollection, from back when I installed this system, that there are
something special I had to do which related to "radeonkms", so I do believe
that that is the one I am using.

That having been said, I looked at my /boot/loader.conf and my /etc/rc.local
and my /etc/rc.conf file and there is nothing in any of those that mentions
radeon.

Here are some lines from /var/log/dmesg.yesterday that may perhaps be relev=
ant:
