Lombard Rage Pro acceleration in 10.2.1

As the owner of an aging Lombard, I was really excited when the hint for accelerating the Rage Pro LT card was published. Then 10.2 came out, and the hack needed to be repeated. But now we also had to update the extensions cache with the command (as seen on Accelerate your Mac):

 % kextcache -k /System/Library/Extensions
Now, sometime around updating to 10.2.1, the driver was lost again. Sure enough, it had been removed from the info.plist file in the ATIRagePro extension. After hacking the info.plist file again, and re-running the kextcache command, and then rebooting - still no graphics acceration.

It turns out that the machine did not update the Extensions.kextcache file in the /System/Library folder after all (as seen in th modification dates). Remove this file, and reboot then everything works great again. Getting rid of this file is not easy - you will probably need to use this terminal command:
 % sudo rm /System/Library/Extensions.kextcache
After that, you should be good to go!
