missing /sys/class/drm/* on official Fedora kernels

starting with 4.19.5, all my fedora kernels fail to get edid info during boot
and are consequently missing /sys/class/drm/*
so graphical resolution is degraded to vga

Ive not really concerned myself too much with it,
cuz Ive been building my own kernels from kernel.org, and they pick up EDID

fwiw, I start with fedora.config, and do localmodconfig.
iiuc, this reduces module builds to those usable on the hardware?

and its an old box, or someone else would have noticed

vendor_id : GenuineIntel
cpu family : 6
model : 23
model name : Intel(R) Core(TM)2 Duo CPU     E7400  @ 2.80GHz
stepping : 10
microcode : 0xa0b
cpu MHz : 2792.715

but in the ensuing months, grub2-mkconfig is failing to update
grub.cfg properly,
so its slightly more tedious, and I should start investigating proper fixes.

You have the causality backwards.  The applications can't get the edid 
info because the drm directory is missing.  What graphics device do you 
have and which driver is it using?  Are there any messages in the log 
(journalctl -b) that mention drm or graphics or fb (framebuffer)?
