Comment # 2 on bug 944059 from Felix Miata

I have a Kaveri temporarily in my possession with HDMI output video working
passably in 42.1 with both 1360x768 and 1920x1080 modes whether using
ati/radeon driver or modeset driver built into the Xorg server. I do see
occasional tiny bits of corruption running radeon @1360x768 that I don't
remember seeing running modeset.
