I used the official image without firmware but was expecting that using isenkram-autoinstall-firmware afterwards was equivalent. >On the kernel side we should try to fix the blank screen with an >earlier check for firmware in nouveau, similarly to the way we patch >the amdgpu and radeon drivers.

At the end of August or beginning of September I can do an install using the image with firmware but I'll suspect that the results will be the same, because the needed firmware is not in Debian non-free either (card not supported in Bullseye). I think that nouveau should somehow output that message (card not supported) so the user gets a hint about what's happening.
