Comment (by kallisti5):
hrev43767 is reported to not fix the issue. It looks as though while we
pass the proper video mode as the "preferred mode", the lack of the mode
in the displays VESA edid data is preventing it from being selected.
The solution I think is adding the preferred mode to the list of available
video modes (even if the preferred mode ends up being the only available
resolution for a lvds display)
