It's possible, but not likely. The bios claims you have local flat panel
(LVDS) and a DVI-I port. Is that what your laptop has?

In those days there was a bug in the connector table parsing where LVDS was not
detected on properly on ATOM systems, so you had to force it with the
monitorlayout option otherwise it would ignore the panel altogether.

What do you mean "first connector"? LVDS always uses the first display
controller right now even though either could drive it. Also, from your logs
it appears you don't have any other monitors attached, so it's the only thing
Some LVDS panels are very picky about the timing they get and the power up
sequence. This seems to be the case with yours. You might try Dave's
drm-radeon-testing branch, specifically this commit:
and see if it helps.
