Just to make sure: you did "cat /proc/fb" and got no output, rather than
"ls /proc/fb" and seeing a file with size 0, right?

So i915 is loaded, but does apparently not work.

No, you're not, otherwise the vesa driver would refuse to load. What
does "dmesg | grep -E '(drm|i915)'" print?
You should have a file /etc/modprobe.d/i915-kms.conf with content
"options i915 modeset=1", is it there?
