  Thanks for the feedback. I understand it is natural do move several
things to kernel mode, so that register level programming is done in
the kernel, as well as video memory management.

  It is because it requires a special version of mesa, and in this case,
a (non official) branch that I believe will work only with the nouveau
driver. And I am not sure if gallium will be the "upstream" mesa at some
(short?) time.
  Once it is compiled it works of course, but my experiences were not
the most positive, I am sorry. So, for the moment, when using nouveau,
I just compile the kernel module to make the driver happy, and start,
but I know it is only functional for 2d.
