backing up my 64bit image to revert to 32bit (minimal flavour).

need to do this so that I can run for more performant video playback.

```mpv --vo drm --fullscreen video.mkv```
worked to some extent (image visible) but complained about no accelerated yuv420p to bgra conversion, hence super slow, and I couldn't convince it to decode as grayscale (the video in question is monochrome anyway)

anyway after last updates the X GUI on the debian buster install was completely broken:

```[ 65.658776] vc4_v3d 3fc00000.v3d: Failed to allocate memory for tile binning: -12. You may need to enable CMA or give it more memory.```
