Thanks - sounds exactly what I was searching for!

So if someone is interrested in writing it there could be also X11 
accerlated pixmaps or even pbuffer/ext_framebuffers based image-surfaces?

Are there plans to include assembler drop-in replacements if a volunteer 
writes it?
It would be nearly free, and if a volunteer is not willed to keep it 
up-to-date you could remove it withouth any problems.
