@farski, are you going to try to get speedstep working? We need to identify a difference between bios versions e758_sz2z and e758_44 that is causing AppleCPUPM to panic, despite our setups meeting it's requirements otherwise. Not sure how to figure that out. Then if we manage that, we have to see if we can do some sort of override, assuming that the cause is the same across all post version 44 evga x58 bioses.

@neptunet, you probably don't have your DSDT quite right. The hangup is probably related to the AppleRTC errors you're getting, so look at your RTC device in your DSDT and compare it other peoples. It should say what bios version you have on the bios boot screen, or on one of the bios setup screens.
