In text mode, instead of blanking the screen and shutting it down, it
is instead painted white, backlight going full steam.
I have bisected the code and git tells me the first bad commit is
f3728734ba78310525bf4a361c7787c7c6fa5d40.
Apparently my laptop, despite having atom tables, still needs legacy
backlight controls. Or whatever.
----------------------------------------------------------
drm/radeon: add backlight control for atom devices (v2)
On systems that use the build in GPU backlight controller,
we can use atom tables to change the brightness level.
v2: use firmware flags
----------------------------------------------------------
And the details at

I was first enthusiastic about using some textmode goodness, but
unfortunately have to return to X11, under it everything works okay,
strange but true.
