No, that's not a misprint for 5mp (i.e. 5 megapixels), it's SMP - Symmetric Multiprocessing. You may remember that Nokia's flagships, the N95 and N82, both have dual CPUs? This didn't really have as much effect on performance as their (also unique) graphics acceleration, but every little helps. However, SMP seems to be a technology that will make a bigger difference in the future, according to an interesting interview with Symbian's Jason Parker, over at SymbianOne.
