Alright, I fixed this now. Turns out it was just me being stupid and
missing a couple of png files (like a file with a lock) from the
original theme. Rereading the log linked above helped realizing that.
I'd like to thank everybody who suggested solutions and helped us
getting a working graphical boot screen for this release of the Sugar
on a Stick spin!

>From how I can currently see it, one needs to execute
plymouth-set-default-theme in %post and rebuild the initrd then. Looks
like it's easier in the end than I tought it'd be. If anybody's
interested in getting a wiki page on that, I'll be happy do work on
that.
