You've mis-built something then; these extensions aren't easily
disabled. Shape, in particular, has no driver component, and I don't
think you can even turn it off in the build anymore.

That's a hardware limitation; removing the overlay saved a pile of
gates.

Yeah, the docs are full of non-Intel trade secrets. I'm working to get
some cleaned up versions published, but it will take the time an energy
of the hardware folks who are rather overcommitted these days.

The 965 hardware vertex shaders have been supported under Linux since
the hardware shipped. We've also recently published an early GLSL
implementation for 965, and are busy working on XvMC support for 915/945
and 965. It's a lot of work writing video drivers (obviously, our work
would be far easier if other people could help, which is why I'm eager
to get docs published...)
