Hmmm, may I  amend this sentence?  I'd  rewrite it as "The  KGI driver
should  support whatever  the  hardware supports   and  that cannot be
handled safely and efficiently in userspace".  Do you agree?

SGI hardware needs almost no kernel support.

What if the hardware itself does backface culling ?

Or maybe we need another library to  abstract the geometry engine part
of modern hardware?

  OG.
