Due to the advanced production process of the cell processor, only 7 SPEs are "active" in the PS3. You could look it up in IBMs tech notes to see a more technically explanation to it.
Edit:
Quote from Wikipedia on the Cell processor inside the PS3: "A seventh runs in a special mode and is dedicated to aspects of the OS and security, and an eighth is disabled to improve production yields."

So, essentially, "advanced production processes" means that when they needed to start making PS3's they couldn't manufacture enough chips with all 8 SPE's working to meet their production targets. So they released the console with a version of the cell with only 7 SPE's working.
