Hi John,
well, this warning is intentional.
The key point is that your random config results in a very suboptimal
situation where the graphics driver only barely work.
And radeon is pointing that out with this warning. That is totally
expected behavior.
Regards,
Christian.

Is anything being done to fix it? I don't see anything in -next or on
dridevel list recently which it could be.
