it looks promising during the boot -v phase but mavericks never loads the edited kext
whatever you edit doesn't even show up in the system info yes/no extensions screen,even after fixing with kext utility.
lion used v6.x geforce drivers,mavericks uses v8.x
I was able to rip the nvenabler.pkg from the iatkos l2 install dvd but that made no difference.
I may track down mountain lion drivers to see if they work.
