Seems like /dev/fb0 is not found when lightdm runs (see http://paste.debian.net/971349/) but it does exist when queried manually. Manually restarting lightdm fixes the boot up issue. ( sudo service lightdm restart)
I thought I would add this to rc.local, but rc.local is missing, I guess I need to create a service for this. Anyways, this seems like a temporary fix. Any suggestions on a permanent fix would be appreciated.
