Not that I can think of. Thing is, automatic partitioning should always set up an 8Mb PReP partition on the driver you're trying to install to. There are no special cases depending on the subtype for ppc64el; and you didn't boot with powerpc (which could have had special rules).
In 14.04, ppc64el uses the same rules for partitioning as ppc/chrp_ibm, which also always creates a prep partition. In other words, even if it's not being used, the prep partition is always created on the systems; there are apparently no exceptions. Looks like what is happening might be that due to the partitioning setup used (do you set up RAID too?), and probably in part because of bug 1487365, the wrong partitions are set with the prep flags, and sdb1 doesn't get it (even though it's already set up as a PReP partition of 8Mb size). When did you last try the install?
