OK, I just found some details on this attack... Not much regarding how they used the PS3s though:
They performed 2^51 MD5 hashes using 200 PS3s for 18 hours, or 173 million hashes per PS3 per second.
For comparison, the previously mentioned GPU algorithm calculates 200 million hashes per second (Configuration: GeForce 8800GT and Core2Duo E6750 using one core)
