Touchpad problems

Hi. My Laptop used VoodooPS2 kext but for some reason I tried SmartTouchpad kext and now my trackpad performs really weirdly. I tried reinstalling Voodoo PS2 kexts in S/L/E and in EFI/CLOVER/kexts/other, but that didn't work. Two finger scroll is too fast (changing the speed doesn't work), moving the mouse around selects stuff, etc. If some of you could help, I would be delighted. My Laptop is: HP Probook 6360b
