Do you have the instructions to build Xorg with the toolchain?

If we work on having x.org server working on the FR, wouldn't that help for
whatever comes next?. At least we would have some working knowledge on how
to develop drivers for X, and a team of programmers with ample knowledge on
all things regarding the x.org Server.

I mean, the thing is modularized. Is it not simpler to just replace the
glamo driver with the [whatever\] driver?

Re: Calling interested Glamo OpenGL developers (was: The forbidden topic: Glamo OpenGL)

You can count me in. I have experience doing kernel development. Since the
documentation is not available, I saw a couple of pointers on how to start
on the nouveau project. They have an excellent section on tools and
documentation. http://nouveau.freedesktoplorg/wiki.

I have some questions, the glamo chip contains 3d support, what version of
OpenGL (or OpenGL ES) is implemented?
Are we still going to keep Xglamo (kdrive) or are we goint to use X.org
server? (this question arised after Rastermans e-mail)
Are we going to support full OpenGL or OpenGL ES on the implementation?
Or is it going to be a OpenGL driver and a OpenGL ES driver?

Thank you
