Had a quick look at updating to 10.7.4, and so far it seems the issues lies in AppleACPIPlatform.kext again, so just replace that and see how it goes. Your system should boot fine afterwards, but there may be a few smaller issues which remain. One such issue I’ve noticed is that somehow I’ve lost internet connectivity.
If you want, just wait until tomorrow/soon and I’ll update all the fixers etc, and I’ll make sure to have an internet fix too!
Oh, and I’ll keep updating this post on what I find, so keep watching this space.
