I tried booting into single user mode
# modprobe i915 modeset=1 # This made my tty use a framebuffer
The result was the same: Blank screen, Ctrl-Alt-F1 doesn't work, not

(I think it's the same, but I didn't check.)
But I noticed:
# grep EE /var/log/Xorg.0.log
(WW) warning, (EE) error, (NI) not implemented, (??) unknown.
(II) Loading extension MIT-SCREEN-SAVER
(EE) intel(0): Failed to set tiling on front buffer: rejected by kernel
Is that a problem?
