I have the same card, and I have used it mostly successfully up to
NetBSD 9; with 10 I started to have complete display corruptions and
stalls after a few weeks of uptime (i.e. very hard to debug). I never
used the amdgpu driver, as I understand it it is for newer AMD cards.

Up to 9.x I used Driver "radeon".

=46rom 10.0 on I used Driver "modesetting", which potentially needs Option
"kmsdev" "/dev/dri/card0" when I enable both the Radeon and the
on-board Intel graphics chipset in the "BIOS".

The reason to switch to modesetting was that something didn't quite work
any more, but it seems I didn't write down what it was.

If you don't have the Device section in xorg.conf, and want to determine
=66rom the log file which driver was used, you have to look carefully.
Lots of drivers are loaded, but also a lot are unloaded again and not
used. Unfortunately you left that part out of your logfile fragment, but
=66rom this single line I think you were using the radeon driver:

I am curious if you also get the corruptions with the "radeon" driver. I
had to switch to the integrated Intel graphics, but that lacks support
for whatever x11/redshift does, and also I can't use mpv in gpu mode,
but I have to use "vo=3Dxv" in ~/.config/mpv/mpv.con. Likewise, wip/golly
doesn't display its life world. So I'd rather switch back.=20
