I've tried both Wheezy (7.5) and the latest Jessie PowerPC64 installers.  Neither one aligns to 1MiB.

Previously in this thread I gave my analysis of the partition map from the Wheezy install.  I just tried a Jessie install and got the identical same partition map.

Bottom line: It doesn't align to 1MiB boundaries. It doesn't even align to 4KiB boundaries.

I think we can do better than that!

Next step is to try it on a i386 machine.
