That sentence should have been in the past, it does look like documentation has been landing in the tree this year ! yay ! I'll go off read it.
We've been building up that documentation for years now, not sure where exactly you've looked in the past ;-)
And to make sure you're looking at the right stuff: Please run
$ make DOCBOOKS="" htmldocs
and then look at Documentation/output/gpu. Otherwise all the kerneldoc stuff isn't pulled in, and a lot of the overview sections (not just abi/struct docs) are in there.
And if something looks fishy or doesn't make sense, please raise it here or on #dri-devel on freenode so that we can improve the docs. -Daniel
