It is probably not directly related to the ATOM, I have an ASUS netbook
with the 510 CPU using the 915 driver, a firewall box based on micro-ATX
and another 510, same driver, and neither shows a phantom video device.
Do you get boot information on the mobo console output? If so you at
least will be able to edit the boot command line. On small systems like
laptops and tiny utility boxen I often have to add 'nomodeset' to the
boot command line, or even remove rhgb to get a boot.
Clearly you are seeing something as it boots, or you wouldn't see the
xorg lines (unless you are coming in from another system post boot).
Any additional info might be useful, I can only say the ATOM doesn't
have a generic problem with Linux or Fedora. I have one other ATOM box,
it runs headless, so I don't remember what the console driver was, other
than 'working.'
Probably related to the nonexistent internal panel - LVDS1.
/boot/grub2/grub.cfg:
linux /vmlinuz-… video=LVDS-1:d,
eventually i915's param - panel_ignore_lid.
