--- Comment #19 from Scot Doyle <lkml14 at scotdoyle.com> ---
It looks like the chromebooks aren't adding the backlight control because the
VBT size check passes but the VBT says there is no backlight.

Do we know of any other machines besides the chromebooks with this exact
problem? If not, maybe a quirk would be the best approach? I think I know how
to identify the machines in question.
