This bug seems to be related to https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/770371 (actually, that bug is related to a kernel bug)
In that case, the intel driver (i915) wasn't loaded before plymouth, here, it looks like the radeon (?) driver wasn't loaded before.
The message in post #3 by skewty is harmless and also occurs on machines with a working plymouth splash. The problematic line is:
[./plugin.c] load_driver:Attempting to load driver '(null)'
