Injectors (like NVEnabler.kext), EFI Strings, DSDT patch are not drivers. It's a way to use orginal MacOS drivers with PC card. The final effect is the same, and there is no advantage in how it works.
Injector is easier to install. But DSDT patch or Chameleon's graphic enabler feature is more "clear" method then kext.
If you download new drivers from this link, you should be able to use it just like previous drivers - of course still with your DSDT patch.
