I went ahead and tried to reinstall the AppleNForce kext and decided to start OS X with -f -v, to force the kext reload and to see the errors. I got a couple AppleIntelATA errors that I couldn't really read quick enough, but I also got an AppleNForceATA error. It said it found 0 units and then gave a message saying, "phy connection failed 0x0000000". OS X still detects the discs in System Profiler, but I still cannot mount them.
