You can try using the kext "ElliottForceLegacyRTC.kext" if you don`t have a DSDT with RTC patch...
If you have a DSDT with RTC patch, you need to "bin patch" your AppleRTC.kext by running the command below on a terminal window (and also, remove SleepEnabler.kext from your system)...
WARNING: Backup your "untouched" AppleRTC.kext first and after reboot, boot using -f -v flag`s.
Code:
sudo perl -pi -e 's|\x75\x30\x44\x89\xf8|\xeb\x30\x44\x89\xf8|; s|\x75\x3d\x8b\x75\x08|\xeb\x3d\x8b\x75\x08|' /System/Library/Extensions/AppleRTC.kext/Contents/MacOS/AppleRTC
