As confirmed by Jaak, disabling DRM_SIMPLEDRM makes things work fine again. So I guess the reason: When SIMPLEDRM takes over the framebuffer, the screen is blank (don't know why). And before 60aebc9559492cea6a9625f ("drivers/firmware: Move sysfb_init() from device_initcall to subsys_initcall_sync") there is no platform device created for SIMPLEDRM at early stage, so it seems also "no problem".
