Not a bad idea, although I *think* that the class of bugs it'd detect
don't overlap with the class of bugs that would trigger apport.  Invalid
xorg.conf's result in a normal server exit with an error message.

Instead, what I was thinking is hooking it into the new bulletproof-x,
because invalid xorg.conf's are definitely one of the use cases that
triggers that.  (Probably as a user-selectable option "Validate
Configuration").  But the first step will be to get this script into the
x-kit package, and get x-kit into main.
