This will probably require a bunch of back-and-forth to debug. You can use gdb to work out why the load is failing. If it's in dri_fill_in_modes, then something went wrong in your downgrade. Feel free to join #nouveau on irc.freenode.net to discuss. -ilia

In case anyone's curious about 30bpp framebuffer support, here's the current status: Kernel: Ben and I have switched the code to using a 256-based LUT for Kepler+, and I've also written a patch to cause the addfb ioctl to use the proper format. You can pick this up at: https://github.com/skeggsb/linux/commits/linux-4.16 (note the branch!)
