Managed to get it working. I used kext Wizard to install it (http://wizards.osxlatitude.com/kext/kw.zip). Kext Wizard installed it into /System/Library/Extensions and there it works fine. If I move the installed kext back into /Library/Extensions it no longer works, move it back to /System/Library/Extensions, it’s fine.
