#11254: Intel graphics randomly boots with black screen

This is hrev 47865 on a thinkpad x230 with intel HD 4000 graphics.
Two thirds or three quarters of the time this machine has a black screen
on boot (with the intel driver). The rest of the time it boots normally
and has the correct resolution etc.
The attached syslog is from 2 boots - the first exhibited the problem
while the second was a successful boot.
More info:
Changing display settings once booted can also cause the same issue
(screen goes black to change modes and the image doesn't come back). This
is mostly a problem with software that changes the screen mode itself
(like SDL apps), since they change without a "return to previous settings"
timeout. Actually, SDL apps seem to change the mode to the same as it
already is for some reason, but I know the mode has changed because of the
flash to a black screen and then back again, and afterwards switching
desktops will cause the screen to turn briefly black then come back,
unless I use screen preferences and apply to all desktops.
