The P3 and P4 series (which includes the P2040, confusingly) use the e500mc core, which has userland compatibility with the existing OpenBSD powerpc userland. The P5 series uses the e5500 core which adds some 64-bit things but is backward compatible (if memory serves then you could even expect a kernel compiled for e500mc to run on an e5500, but I'm not 100% certain). The harder thing is to find something out there that uses a P2040, P2041, P3041, or P4080 to get started with. -- Matthew Weigel hacker unique & idempot . ent
