I don't use Freescale chips, but I do use the Powerpc architecture all of the time. I work at IBM on the GCC compiler for the powerpc architecture. At present, our current released server machines are power7/power7+ with a lot of work for the new power8 server platform that will be coming.
In addition to automotive field, I know powerpc also had design wins for set top boxes. But since I don't track that end of the market, I don't know who the major customers using the embedded powerpc boards are.
