So overall we (only) need 5 additional kernel modules: i915,

Re-used/adapted some logic in debian-installer.git, see speech-support
branch (the commit message sucks, and at least that would need some
editing before merging into master).

See kibi/for-master for the debian-cd side (patch 2/3 compared to
current master).

Test image:
   https://people.debian.org/~kibi/bug-1092977+intel/

(also contains partman-crypto fun, unrelated, but one build/stone, two
bugs/birds, right?)

I've at least confirmed I can `modprobe i915` manually…

I can't do `modprobe i915`, not even `modprobe drm_buddy`.
I get the error message:
modprobe: FATAL: Module drm_buddy not found in directory /lib/modules/6.12.29-amd64.

The kernel module files are present, `modprobe /lib/modules/6.12.29-amd64/kernel/drivers/gpu/drm/drm_buddy.ko.xz` works.

So I booted the graphical installer, opened a terminal with Ctrl-Alt-F2 and ended up with modprobe commands with a path for all modules... Finally I could modprobe i915 and as proof it worked, the resolution of the terminal changed and dmesg showed the addition of a sound card.
(When I did this in the shell within d-i, the computer hung up)

Looking at the WWW for this issue: Is a call to `depmod` missing?

So I booted the netinst image again, the combination `depmod;modprobe i915` (in a console) worked like a charm.

However, I'm a bit surprised by having kernel 6.12.29 in the test image.

I tested with kernel 6.12.27 (as that is present in the RC1 image), because I assumed that 6.12.29 would not migrate to trixie due to #1106070 (which would break all live images)

So in summary:
* The netinst image needs `depmod` for the added kernel module(s)
* I didn't test the espeakup yet, but assume it will work
* I hope we will have kernel 6.12.30, but definitely not 6.12.29

With kind regards,
Roland Clobus
