Xorg -configure ... Segmentation fault at address 0x0

[Ronald F. Guilmette]

I would like to respectfully suggest that the Handbook section 6.3
(Installing Xorg) be amended so that near the very beginning it
tells people to pre-check the compatability of their GPU against
the "Tested hardware matrix" list provided here:

This would have saved me a lot of time and bother, and perhaps
would have done likewise for lots of other people also.

(I will file a formal PR for this suggestion, unless anyone feels
that it is dumb idea.)
