Let udev auto-load display modules when RP1 PCIe southbridge appears on the bus (~12s). This is exactly how Rex's Debian image works — no forced loading in initrd or stage-2. - boot.initrd.kernelModules: only ocp8178_bl (backlight only) - boot.kernelModules: no display modules (udev handles it) - SDDM disabled (Hyprland kept for manual start)
