dmesg 4.18+drmtip with i915.ko just in the root fs

$ grep "re-using BIOS fb" *tip*
dmesg-4.18-drmtip_initramfs:[    1.727499] [drm:intelfb_create [i915]] re-using
BIOS fb
dmesg-4.18-drmtip_rootfs:[   19.842296] [drm:intelfb_create [i915]] re-using
BIOS fb

1. i915.ko in initramfs: works as expected (splash animation from boot)

2. i915.ko loaded late from rootfs: I still just see the splash image for a
second and then have a black screen. If I switch the VT manually, I can switch
to the correct splash image, which is no longer broken.
