I've just finished setting up a laptop with a Ryzen 7-3700U (RX Vego 10)
and it's working (though I'm running 13-current and drm-current-kmod).
Possibly you need to use drm-devel-kmod, rather than drm-kmod.

This should be unnecessary.  I suggest you delete the xorg.conf.

By default, xorg doesn't include the amdgpu driver.  Since you are
loading the amdgpu kernel module, you should have KMS enabled and
xorg should default to using the xorg modesetting driver.

I don't see this message anywhere in the followup you posted.  I do see
"Warning, couldn't open module amdgpu" - which is what I'd expect.

That [drm] line is expected and should be followed by another ~100 lines
of drm-related output.  This information will be in the output from the
"dmesg" command as well as on the console.

What do you mean by "nothing happens"?

If X still doesn't work after you delete xorg.conf, could you please
post your Xorg.0.log and the dmesg output starting with the line:
[drm] amdgpu kernel modesetting enabled.
