oh, that's true, and this patch doesn't aim for that. This patch trys to
not add more LVDS quirks for different kind of OEM boards, which has their
own customization. As current driver has no idea if LVDS exists besides quirks.

If you have a machine original needs a quirk line in src/i830_quirk.c for LVDS,
you can try with this patch and remove that line. Or you have other models need
to ignore LVDS.
