There are two formats for the 24-bit LVDS data, one is backwards
compatible with 18 bit panels (all the color LSB info is on the 4th
link), the other is not backwards compatible. IIRC the display
enable, hsync, and vsync are in the same place in both, so you can
hook it up, and if the colors look very weird, you have the wrong
style output.

In here http://www.intel.com/design/intarch/papers/315975.pdf table 3
and table 5 show the difference.
