UPDATE:
I'd have to recommend that people NOT install the entire update- it really is hardware-specific, and breaks things like optical and USB. If you need to install anything from this package, update by installing indiv. items through Pacifist.
10.7.3 Kernel & Powermgmt kext installable through Bridgehelper.
