dmesg of intel drm nightly 20160512 with fastboot=1 dsi display not working

This is getting interesting. While fastboot=1 makes the dsi display working on
4.6rc4, it doesn't help with the intel-drm-nightly 20160512, where the screen
goes blank when the modesetting happens. However fastboot=1 makes the WARNING
go away.
