No, I don't think it is a good idea. Kernel's should provide the minimum
layer needed to securly and efficiently implement solutions in user
space. The DRI has a kernel component to access the graphics
hardware. The rest of OpenGL is in user space.
There are lots of advantages to doing it this way:
1) The kernel remains small. No wasted memory. Less security
problems.
2) You can layer different graphics systems on top of the same
kernel interface. (For example the Xv guys wanting to use it)
3) It easier to change, debug, etc.
There's essentially no advantage to having X or OpenGL in the
kernel. Do you really need 3D during boot? I'd say no. It can wait until
you mount a file system. If you want to get graphics running earlier in
the boot sequence, go right ahead and work on that.
