From memory, David claimed you cannot directly work on the fb with a "proper"

DRM driver. Maybe I misunderstood but then the DRM shines by its complete
absence of useful documentation 

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.
