What are Bookworm users supposed to do to make Mesa DRI work correctly
now that i915_dri.so is missing? Did it get moved to some other .deb
I can't ID? I don't think Crocus is supposed to work on Gen3. At least,
export MESA_LOADER_DRIVER_OVERRIDE=crocus in /etc/X11/Xsession.d/10-crocus.sh
doesn't help.

In openSUSE Tumbleweed in 22.2.4 i915 is still included in its Mesa-dri
package, and Mesa DRI Intel 945G is working as expected.
