   4 Subject: [PATCH] xf86pciBus.c: use Intel ddx only for pre-gen4 hardware
   5
   6 Use intel ddx only on pre-gen4 hw, newer ones will fall back to modesetting
   7 Author: Timo Aaltonen <tjaalton@debian.org>
   8
   9 Instead of defaulting to the Intel driver for all Intel hardware, only
  10 default it for older hardware for which it has shown to be better for.
  11
  12 Others fall through to the -modesetting default.
