As expected, some hacks are required: I had to change ubiboot parameters, and issue fbset in userspace, but the biggest obstacle seems problematic display panel drivers. I get warnings from kernel and "Framedone not received for 250ms!" after those warnings. I'll have to spend some more time to figure this one out...
