I also encountered this frustration. Couldn't even boot into safe mode and none of the Advanced Boot options could help either. Wish there was a searchable method of manually removing the driver but I found none and had to re-install Windows 7. This was especially frustrating because both the computers I built for my extended family had the same hardware setup - and the update killed them both. I'm currently re-installing Windows 7 on both and removing this update from the Windows Update options. I'll be sticking to Asus' website and direct my family not to use WU for driver updates anymore (which is rather disappointing in my opinion - why even offer them up if they're not going to work OR much worst: force a Windows re-install?)
