MPI5001 and RPi Zero 2 W and MoOde Audio

[MeatLasers]

I have some issues getting the MPI5001 working well on the RPi Zero 2 W with MoOde Audio.

It is not the a hardware problem, because when I just use the RPi Zero 2 W with Raspberry Pi OS Bookworm, everything works nicely out of the box. I don't need to change the config.txt or install any drivers. The touch screen is nice and snappy.

However, when I try to use it with MoOde Audio my struggles start.

1. Without editing the config.txt, the display shows the bootlog, but in unreadable small text. When MoOde starts the X11 interface, the display switches on/off, shows sometimes a white screen, but nothing happens.
2. when adding the following to the config.txt:

    max_usb_current=1
    hdmi_force_hotplug=1
    config_hdmi_boost=7
    hdmi_group=2
    hdmi_mode=1
    hdmi_mode=87
    hdmi_drive=2
    hdmi_cvt 800 480 60 6 0 0 0

The screen works, but is extremely slow. The touch has a delay of about 3 seconds. The screen has a delay between 5 and 30 seconds. Completely different than with Vanilla Bookworm.
3. When I run sudo ./MPI5001-show I get the following
grep: /etc/lightdm/lightdm.conf: No such file or directory
/usr/bin/raspi-config: 2049: [: Illegal number: W1
/usr/bin/raspi-config: 2052: [: Illegal number: W1
/usr/bin/raspi-config: 2059: [: Illegal number: W1
/usr/bin/raspi-config: 2067: return: Illegal number: W1
This comes from "sudo raspi-config nonint do_wayland W1" in the system_config.sh
Performance of the touch screen does not improve.
4. When I add "dtoverlay=vc4-fkms-v3d" to the config.txt, X11 of MoOde Audio doesn't start.

Any suggestions how I can make progress here?
