Follow-up:

After a dist-upgrade, the error returned. I deleted the video acceleration
firmware and it was ok again.

When I installed 5.4.14, there were warnings about possibly missing firmware
(the nvidia files from firmware-misc-nonfree), so I reinstalled that package
and updated the initramfs (I think I missed that step after purging the
package). Furthermore, I removed nouveau.config=cipher=0 since that doesn't
seem to be related to the error.

To conclude: When it works, I do a dist-upgrade one day and the error returns.
Doing a dist-upgrade a few days after makes it work again. The same holds for
kernel upgrades.
