I also have the restart after sleep problem with my Asus Rampage II Gene based hack.

I have done some brief tests replacing OpenHaltRestart.kext with Master Chief's OSXRestart.kext (http://www.insanelymac.com/forum/ind...owtopic=199048).

Restart after sleep works with this setup but now the computer doesn't shutdown fully. I suspect that there are further changes needed with the DSDT and/or kexts in order for shutdown to work with OSXRestart.kext.
