Use intel ddx only on pre-gen4 hw, newer ones will fall back to modesetting. Instead of defaulting to the Intel driver for all Intel hardware, only default it for older hardware for which it has shown to be better for. Note that Debian/Fedora and their derivatives, as well as the yocto project have been carrying this patch for many years: https://salsa.debian.org/xorg-team/xserver/xorg-server/-/commit/192254841ab79e102c18fc299f18af0e27d5b517 https://src.fedoraproject.org/rpms/xorg-x11-server/c/ee515e44b07e37689abf48cf2fffb41578f3bc1d so this simply aligns xserver upstream with Linux distributions.
