Well that part is true, which is totally to do with lack of developers
working on it in the correct direction, as I said lots of us know how
to do it and what direction it needs to go, lots of us however have
lots of other things that keep us occupied that are more urgent now,
the problem is for 90% of things the current systems work, so getting
the momentum to redesign a complete system just so root can't get root
is always going to be difficult... the people who care about the 10%
haven't contributed their time other than to complain about the 10%,
which puts them in the don't care category for the people trying their
best to please the other 90% with limited resources.

Your problem is you never listen when someone tells you, you can't
break things, your solutions all took the easy path which is to bust
fbdev or make it require DRM, which isn't what people want, there is
no politics here other than Linus stating you can't break working
systems and trying to figure out how to do it technically, of course
it is going to be more work and of course most of the work might be
thrown away in two years, but that happens a lot transition code is
very important. The amount of dirty work I've  had to do to get the
r300 stuff so that the DRM doesn't break current systems is an example
of this, you would have just said, well let them fix X, I however
cannot accept that answer.

Dave.
