This seems the sanest.
Or go the intel glamour route and stitch together a somewhat generic 2d accel code on top of GL. That should give you reasonable (albeit likely not stellar) X render performance. -Daniel
I'm not sure that would perform well on a tile-based deferred renderer like Mali. To perform well, we need to gather an entire frame's worth of rendering/draw-calls before passing them to the GPU to render. I believe this is not the typical use-case of EXA? How much of the framebuffer is re-drawn between flushes?
