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.
I've seen that in one other case, where what was in fact happening was that forcing the connector "off" was actually effectively leaving it as the BIOS set it.
When I use LVDS-1:d in the kernel command line, that connector is not shown by utilities such as xrandr, at all. There is, however, another connector, named LVDS-0, and are also DVI-0, DVI-1, and DisplayPort-0, DisplayPort-1, while this mobo only have DVI & D-SUB (and LVDS soldered on board too) and no DP. At least as far as I can see. So at least one LVDS connector is shown anyway (LVDS-0, not LVDS-1), and that one is "not connected".
Besides, DisplayPort-1 is shown as "connected" by xrandr, with monitor set to 1024x768 mode, -- I think this is why the text VGA size is calculated wrong.. Lemme see...
..nope. Adding video=DisplayPort-1:d to the kernel command line (in addition to video=LVDS-1:d) makes no difference, DisplayPort-1 is still shown by xrandr as connected @1024x768.
What happens if you then use xrandr to change thedisplay sizes ?
X11 works fine as far as I can see. Xrandr works and changes video modes. Once I switch from X back to the text console the text size occupes 3/4 of the screen only, as if the monitor was smaller.
I wonder if it will work with more than one monitor... ;) I'll try hopefully today.
