That's very true.

I wonder, should i965g be built by default?  Or should you have to 
explicitly request it via --with-gallium-drivers=i965?  The thinking is 
that the default should be to build the drivers most people want to use.

We could also make ./configure print out a warning message saying 
something like: "The Gallium i965 driver is highly experimental and not 
supported by Intel.  Intel recommends using the classic driver 
(--with-dri-drivers=i965)."

Those are just ideas.  I'm open to discussion.

I agree, that would be interesting.  It'd definitely make for a more 
compelling classic vs. gallium comparison.
