missing /sys/class/drm/*

I just upgraded an old box to fedora 29 model name : Intel(R) Core(TM)2 Duo CPU E7400 @ 2.80GHz when booted, none of these kernels has /sys/class/drm/* populated and all have trouble with graphical mode, I am causally linking these 2 facts, does that make sense? If so, it makes sense to file a bugzilla report, what else should it include ? lightdm/kde work the best, setting screen resolution at minimal VGA gdm fell over, never replaced the splash screen I built an rc3+ kernel, copied f29 config, make localmodconfig, It has /sys/class/drm/* and sets right resolution on boot.
