are you having trouble with getting the kext to load? i was having the same issue, so i deleted all of the intelapplex***** kexts and started off fresh and loaded 2a42appleintelgmax4500 see attached picture 2.jpg
Not really, no. I can run the script without any options, or with -vrf, -rf, -r, i can't remember exatly, but i tried all variations, and even the non forced ones worked fine (at least the script said everything is ok) After reboot i had no messages saying anything about kext errors (i had some with the audio driver, but it was fixed after repairing permissions with osx86tools).
Now that you showed us that corrupted cursor, i remembered that the very first time i ran the script, i could not get the system to boot up, i saw only noise(like on old tvs), and when booting into safe mode, i saw the corruption like yours instead of the mouse. I guess i just had a wrong devid passed with the f option, since i can run the script now any way i like, i alwasy have native res. after reboot, without any kext loading errors, Of course with no mouse pointer.
I was trying to find something about running the mouse in software mode for a while now, with no success.
