Upgrading to 6.5 did fix the problem, and did not (so far) seem to break my 
proprietary software.

For reference, I had already updated the kernel-firmware package (that happened 
automatically), and I could still boot the old kernel, which was how I got 
around to upgrading to 6.5.

More than anything, it's a little annoying that this is such an easy mistake to 
make, and so hard (it seems) to debug. But well, I won't be making it again.
