Having absolutely no idea whats causing the problem

Indeed strange I've now rolled back using btrfs snapshots to before the apt update, which made it work. However, the boot partition is not btrfs and did therefore not roll back. So I noticed the following:

1. With hdmi_safe=1, old system and new boot works (with crappy resolution, of course)
2. Without hdmi_safe=1, old system and new boot does NOT work
3. old system and old boot (taken from a separate borg backup solution) works (obvious, but indicates that I didn't screw up any part of the roll back)
   

Does that say anything to anyone? I guess the firmware update replaces all the *.dtb files in /boot, and that has to be part of the problem, but somehow the system files makes even hdmi_safe not work.
