Generally, /System/Library/Extensions should be viewed as Apples and /Extra/ArchExt (where arch is Mini9 etc) is NBIs. If possible don't muck around in either. Use /Extra/AdditionalExtensions. If you want to replace something from Apple or NBI then remove it from /S/L/E or /E/ArchExt and put your version into /E/AdditionalExtentions. UpdateExtra.app will do the right thing with kexts in AdditionalExtensions and when you upgrade NBI it leaves AdditionalExtentions alone so you'll probably have less repair work to do.
Avoid duplicates in the various places. Only one can be used, I forget what the rules are for selection, but it's always been the wrong one with me.
Avoid when possible using other kext tools as they don't maintain NBIs required cache - use UpdateExtra.
Basically use AdditionalExtentions for your kexts, don't leave duplicates in other locations, and use UpdateExtra to maintain the caches.
