I'm not sure it's worth the effort. Much of the older hardware isn't even capable of EXA (lack of offset-based blitters for solid/copy and the lack of 3D engines for composite). For hw that is, it's a lot of work for old hardware that hardly anyone one uses. I suppose there are a few chips that are still used where it may make sense. In many cases shadowfb is as fast or faster than the blitters on these old chips anyway. XAA is mostly sw rendering now anyway.
