Kext Utility is an easy to use application that allows you to install multiple kext files simultaneously and repair kexts permissions for system's and Extra folders.
Kext Utility also allows you to pack kext files to mkext cache file and unpack mkext cache files.
The utility uses a modified widely applied fast method repairing of all (non/standart) kexts with little improvements.
To all kexts the identical permissions (a little more liberal, than it is necessary) are granted. Though it not 100% satisfies the system's "Disk Utility", however on working capacity of system, to the worst, does not affect.
Note that to run "Disk Utility" when you have enough time is the best way for repair all standart kext.
