That's for a hackintosh, not a real mac. It says so in the readme file. It added kexts (drivers) that can't be used on real macs, hence your boot issues. Not the same as the original made by Bresink.
Can you boot in safe mode? Hold shift when you start the computer. If so, simply delete the fakesmc.kext file (system>library>extensions), then open terminal and run these two commands:
On Lion and Mountain Lion:
sudo kextcache -system-prelinked-kernel
sudo kextcache -system-caches
if you're on SL or earlier, the commands are:
sudo rm -R Extensions.kextcache
sudo rm -R Extensions.mkext
If not, you can do it in single-user mode or just go into recovery (hold option at startup) and reinstall OSX. It won't delete your files, just reinstalls the OS.
