Default DDX build
Neither DDX default build, or when built to default to Y tiled scanout, manage
to do the hardware 90/270 rotation. Instead it falls back to software rotation
and X tiled fb.
Allegedly kernel rejects the setcrtc call DDX makes so perhaps the DDX is not
respecting some of the kernel rules on how this should be used.
I got some old Xorg log for both build flavours showing this which I'll attach.</pre>
