It's only the main processor (PPE) that's PowerPC - albeit one not
designed to run a general-purpose OS due to the lack of branch
prediction etc.  The 8 SPEs are SIMD CPUs which have 64KB local memory
and no direct access to main memory - the program that's running on the
PPE has to send data to the SPE via the Element Interconnect Bus (EIB)
using DMA. 
So once the general-purpose OS is installed all you have ready access
to is a processor that runs like something from 10 years ago.
