bullseye not droping to initramfs

[topuli]

to be clear, this is not a problem of this guide it is a problem that comes with the latest raspberry os version.
to boot into initramfs /boot/config.txt should contain dtoverlay=vc4-fkms-v3d instead of dtoverlay=vc4-kms-v3d

Thanks for this!

i applied this, but on bullseye i get this error on the PI400:

This is a warning about Realtek drivers. As you are building the initial ramfs on the raspberry, you can ignore the missing firmware errors. The other error can also be ignored as long as the new programs are in the initial ramfs. How to check this is explained in this guide.

Can you update the doc for this? I spent a day trying to get it work for bullseye arm64 because it kept on rebooting with initramfs on until I see this.

Perfect guide, however for a headless Pi incorporating a pre-boot Dropbear SSH to allow headless entry of the decryption key would be of use.
