Indeed.  I can confirm that the attached patch fixes that.  I can look
at the submission to upstream.

Indeed.

We really need to fix this for the 10.1 release: since hda-based boards
are very common we are getting more and more reports of people failing
to get speech synthesis (no, they don't read the errata).

What do you prefer?  Including the proposed patch in the Buster Debian
package?  Rather wait for upstream to include the patch, and in the
meanwhile adding i915.ko to fb-modules in Buster?
