Need kexts that work without EFI for system that doesn't support it

[TrentZ]

I'm trying to use 10.5.2 on a machine that doesn't support EFI. For that matter, I need to replace some vital kexts (System.kext, AppleACPIPlatform.kext) with versions that don't need EFI to work correctly.

I'll be very grateful if somebody could provide me those.

Thanks!
