Sorry for not really being on top of the problem you and Eric have been
reporting.
I have been consumed with other OpenChrome related activities for the past few
days.
I think what happened was that when I fixed the DVI to VGA adapter regression
Christopher reported previously (in September 2015), I started to notice that
my Sylvania gnet 13001 netbook's flat panel started to go wrong.
This commit is the one before the fix for the flat panel that does not come
with an I2C bus.

Try that code ("git reset --hard 802544370dd827ed3488965e39804e3cb630888a"),
and see what happens.
I will tell Eric about this temporary if it works.
