vampyrex13, Thanks for your great work!
I'll try your new dsdt and kexts, later.

BTW, My x61 doesn't have trackpad. I was mistaken. That was trackpoint, sorry.

Now, My trackpoint have worked course I put AppleACPIPS2Nub.kext and ApplePS2Controller.kext from /E/E to /S/L/E .
But I don't know why.

vampyrex31, Do you know the reason?
