So to clarify based on IRC discussion:
 - Current trusty (3.12.0-7) gives a blank screen from the start
 - mainline drm-intel-nightly build 2013-12-10 does the same
 - mainline drm-intel-nightly build 2013-12-11 and any further one "works"

"works" here refers to the screen lighting up at boot time and the
system being usable, however any further blanking or dimming of the
screen will blank it for good and require a reboot.
