I already feared that. I tried
Option "AccelMethod" "UXA"
but (as I expected) that wasn't the problem.
How does the driver determine if KMS is available?

When I comment out the line in /etc/modprobe.d/i915, X starts normally.
And I have
root@cassiopeia:~# cat /sys/module/i915/parameters/modeset
Both makes me think that /etc/modprobe.d/i915 is early enough, isn't it?

2.7.0, 2.7.1 and 18.104.22.168 all behave like that. (That is, it works
without modeset=1, and fails with it.)
