As I'm actually one of the people involved in my spare time in the
project, the truth is in the middle. It can run little-endian code, but
it does not have VSX, and its Altivec unit does not operate in little
-endian mode, so without VSX it would make much software incompatible. So even if we could get it to run ppc64el on it, it would be sans
-Altivec optimizations. The choice so far is to go for the ppc64 port
in Debian.
