I took a shot at this. RenderDeprecatedFlexibleBox is actually quite simple. To determine whether or not to do vertical or horizontal layout it just checks if the box has BoxOrient::Horizontal or not.

I tried using RenderObject::isHorizontalWritingMode to make that check for vertical or horizontal flow more similar to other standardized Renderers. However, it looks like the RenderObject bitfields are being set to horizontal writing mode no matter what CSS writing-mode value is specified.

So it's going to be slightly less easy than I initially thought.
