Please read spec OpenGL, OpenGL ES, EGL and all gl related spec are
freely available, and i am sure you can google description of it. As many
other already stated what you want to achieve is requiring a really big
chunk of new code and i don't think anyone here got time to devote to
such project, moreover if such project ever end up in somethings
working this won't be before months, years of hard work. I don't think
this is the way to follow right now. If we ever want to get hardware out
of X handling we have to reach such aim by little improvement, even
if taking off hw management from X might be somethings good, i
don't believe throwing away the X protocol & X server is really a good
solution, maybe you should look a bit more into this, also look at
all previous attempts to get rid off X, i am confident we can say they all
failed.

For OpenGL ES compatible hw i would say that all not so old GL pc graphics
card are able to handle all ES specs, in fact most of them are able to
handle a lot more than ES (as OpenGL ES is a subset of OpenGL), to my
knowledge you won't find any free driver that give you ES, only free driver
capable of taking advantage of 3d hw i am aware off are DRI driver.

best,
