Well, I downloaded the 2.6 version of the Elan kext (https://osxlatitude.com/index.php?app=core&module=attach§ion=attach&attach_id=1862
) listed in the first post of this thread, then put it into /System/Library/Extensions. You can use a kext tool for this, but I just use a terminal window to move the kext over and then use chown and chmod to set the permissions.
Once I did that, and rebooted with chimera (chameleon, stolen and rebranded), I was able to go to System Settings and access settings in "Trackpad".
