For me, I'm fortunate to have installed a very old i810 driver (from Debian sarge version, IIRC) and pinned it at that version. This makes the video work. But as xorg has been developed, I've long suffered from broken XKB support and many other things. And I can't upgrade many GNOME packages due to the dependencies.

Would some code from the old i810 driver help? I don't know about X video driver internals. Just hope (and pray) it helps.
