Ok, I guess someone should write Doc*/fb/inteldrmfb.txt...

I got unaccelerated X working, good.

Section "Device"
Identifier "Generic Video Card"
# Driver "intel"
Driver "fbdev"
Option "UseFBDev" "true"
EndSection

...but when I returned to machine, display did wake up but backlight
did not :-(.

But I still can't get accelerated X to work. I tried updating xserver:

Setting up xserver-xorg-video-intel (2:2.13.0-2) ...

Section "Device"
Identifier "Generic Video Card"
Driver "intel"
# Driver "fbdev"
Option "UseFBDev" "true"
EndSection

but when I try to start X, I get:
