Well, I'm not sure what the remaining differences are.

The only thing I can think of is to compare mmio traces between working and
non-working kernels to observe the difference that I seem to be missing.
There's a guide at https://wiki.ubuntu.com/X/MMIOTracing except that instead of
tracing the nvidia blob, you need to trace nouveau. Add nouveau to your module
blacklist, and boot into text mode. Then start tracing, load nouveau, and stop
tracing. (No need to start X.) Collect such a trace file for both a kernel with
working hdmi sound and non-working.
