Currently linux-solo in Mesa-newtree is a good way to have accelerated 3D
outside X but it uses fbdev as it managing API (mode settings, palette, etc.)
and in reality is a pain.  If you could donate a new managing API for linux-solo
in an OSL that would be a good start.  That could be a good foundation for
an OpenGL backend for xserver and for others projects like mine. Just my
opinion.
