I have been lead to understand that it is not really done yet.
What works is awesome, but it is not all there yet. So I have been told.

I am not surprised. Intel wrote the drivers for 810 for Windows. What
other drivers would you need? Why document it well? :-)

I would love to have a HWOGL fall into my lap. :-) 
I don't think (and this is my opinion only) that we should put bare minimum work
into a software OGL renderer. Basically, they are worthless, since most opengl
is for games, and no one wants 1fps games.
