The precondition obviously is that the kernel driver has the same
HP 2D/3D features as a userland driver. I find it interesting, but
doubt that it will work in practice. It's hard to write and
maintain a portable graphics driver that works with dozens of OSes.
Especially since performance and portability are opposite forces.
