I think you mean disable, not enable, since this is (again, I think) what
video=LVDS-1:d kernel boot parameter does.
Yes, with video=LVDS-1:d boot parameter, kernel boots fine and there is
graphics/video output on the screen, with the following message from kernel
when loading gma500_gfx:
[ 6.472859] [drm] forcing LVDS-1 connector OFF
(and a few others).
There's one funky thing still -- the screen size is not calculated correctly
for the text (vga, d-sub) console, last text line is placed at about 3/4 of
the screen size, with the rest - 1/4 - of the screen being blank.
However, X seems to work fine, using generic modesetting driver.
Below is dmidecode output.
