Okay I got it. I messed up my 10.7.4 install, so instead of restoring from my CarbonCopyCloner backup (yes, it is great) I decided to start fresh from iAtkos L2. The kext that you need to back up and replace is IOStorageFamily.kext. But anyways, I was able to successfully update from 10.7.2 to 10.7.4 so it's not impossible, just be sure to back up and replace that kext.

Here's the kext btw: http://dl.dropbox.com/u/79094064/IOS...amily.kext.zip
