Ah. I think I have confused you guys. I am using the most recent version pf Petsc (ie. 2.3.3 p13). I am trying to get my old code (which I made using 2.0.22) up and running. I have updated most everything and I am trying to run for the first time. Given what you said, I am guessing that I have messed up in a way the causes KSPRegisterAll and KSPRegister not to be called.
