RPI4 issues with fbdev driver and newer Kernel

ARM

We did add /etc/X11/xorg.conf.d/99-v3d.conf file so the pi5 could go into graphical mode in all images. The pi4 uses it but at the time the pi4 did not require it. I have not tested it since with it removed for the pi4.

Section "OutputClass"
  Identifier "vc4"
  MatchDriver "vc4"
  Driver "modesetting"
  Option "PrimaryGPU" "true"
EndSection

Yes, I saw that.
I rebuilt the boot partition, re-applied the updated linux-rpi4 and linux-rpi4-headers using arch-chroot and booted OK

Thanks again.
