You should have not use both nvidia EFI Strings and nvidia laptop kexts, either use an nvidia injecter or an EFI string.
Try removing both and installing some nvidia laptop kext that supports your specific graphics card.
Also you may need to some ps2 support to get the trackpad working.
Also I would ditch the modded ACPI (it should be not needed with current ps2 solutions) and replace whatever kext "laptop battery" installed with voodoobattery's latest version.
