[Intel-gfx] Setting proper video mode

[Jarek]

Hi all!

	I'm trying to setup some strange LCD display which supports only one
mode 1920x480 at 61Hz. It works with old IEGD drivers, but not with
xf86-video-intel 2.15.0. After some changes to source code I'm able to
force the proper resolution, but there is still nothing on the screen.

Is there something beside the modeline, which my affect setting display
mode ? How to compare what is set with iegd that the display is working,
and how to force xf86-video-intel to do the same ?

The modeline is exactly the same, except refresh rate, which in iegd is
61Hz, and in xf86-video-intel is 61.7 - I don't think that such small
difference may affect the display.
