Debian does not include non-free software, including firmware. That's not a bug. You will need to install firmware-misc-nonfree to make the nouveau driver fully functional. However, the driver ought to fail cleanly when firmware is missing. At a minimum it should be possible to boot in text mode and then install a firmware package if wanted. > During a hung boot, I am able to SSH into the box to poke around and > send this report.

Unfortunately the kernel doesn't have an API for re-enabling a basic video driver. There have been similar issues with the radeon and amdgpu drivers, which we patch to guard against this failure mode. We might need to apply a similar patch for nouveau.
