I am assume you're using the right dts. Try booting with a mouse and monitor plugged in - you may be hitting this: https://github.com/maemo-leste/bugtracker/issues/204
What branch did you use for the lime2-linux kernel? The one we ship with our latest images is not using lima (lima also might require dts changes and some .config changes that are not yet online)
In short - are you trying to get lima to work as well?
We were planning to make lima images soon, but it (lima) is still a bit unstable, so it might not very usable/clever to do so.

EDIT: I would prefer to help debugging over IRC or over our mailing list (ML preferred), btw. I check both way more often than tmo.
