Have to step in here and lets take the _but_ .
After a short sleep and a look at the gfxdriver ...

Take the attached patch and you'll get an alpha blended OSD with I420

So I don't know if that still works with radeon, there we need some work
in the directfb driver section.

It works with both directFB pixelformats (AiRGB, ARGB).
