I've added an option for using PPE threads in addition to the SPEs, however the results are somewhat underwhelming. The Cell PPE is effectively a dual-core processor, but even with two PPE threads I only see about an extra 500 Khash/s.
There may be some PPE optimizations I'm missing, but otherwise I'm currently maxed at about 21.983 Mhash/s using all six SPEs and two PPE threads.
For those interested, I've put the source code online:

21 Mhash/s is not to bad I guess...it's not GPU but hey anything extra is a good thing. The downside is that given the PS3's power consumption that has rate may not be economical for the majority of people.
I wonder though how people with the recent generation PS3s would be able to run this miner. I'm assuming that one needs to have linux installed on the PS3 to make this work; no?
