You can run code compiled for the 970 directly and w/o any modifications on the PPE but with some performance loss. Linux uses the Power core to run the operating system and normal, non-Cell-aware applications. It provides SPUfs [1] which allows application developers to use the SPEs. The SPUfs is in the Linux tree it seems, so that could serve as "documentation" but I'm not sure right now if there is public documentation for the SPEs. In order to run FreeBSD on the Cell you'd need a working port for the PowerPC 970 CPU plus possibly some extra bits in order to be able to boot on the PS3. HTH, Phil.
