after install Leo4all my system wouldnt boot either, i replaced AppleACPIPlatform.kext, and AppleNforceATA.kext,(with the ones from Zeph's) then it worked.

It is normal to see "Loading HFS File [mach_kernel]" twice in a row...

also i noticed that running marvins amd utility form another working install found a few more cpuid's that needed to be patched on the fresh Leo4all install
