Comment:
Ok, I'm pretty clear on the issue now. This issue is mostly due to me not
having hardware to test on.
Some implementations require a special AtomBIOS call to pull LVDS panel
information (limits, modelines, etc)
It was a todo, so I just sent back the VESA modeline..
connector_read_edid: LCD panel detected (LVDS), sending VESA EDID!

Interesting bits: (notice the 0 limits)
