Ok, turns out the new firmware can still boot 4.4.x, as long as you 
compile the device tree files from kernel source.
The bundled binary ones only work for 4.9.


Should have known that, as I had already been burned by that before...

BTW is it possible to let buildroot compile dt overlays nowadays?
As the overlays are now also starting to show changes between versions.

E.g.:

https://github.com/raspberrypi/linux/blob/rpi-4.4.y/arch/arm/boot/dts/overlays/vc4-kms-v3d-overlay.dts
versus
https://github.com/raspberrypi/linux/blob/rpi-4.9.y/arch/arm/boot/dts/overlays/vc4-kms-v3d-overlay.dts
