i switched my motherboard to an asus one now which i got from ebay for 25 euros, it got integrated graphics and fast boot (didnt even noticed that)
but i get appleacpi something error with kernelpanic. iam not able to boot in at the moment without deleting the 7000.kext.
we know how to apply these things with fbrotate, but it just stays white for us, when i boot without the 7000.kext i see that fbrotate is executed automatically. but not when i boot with the kext.
Try to put your device id in the kext
