My PS/2 mouse and keyboard not detected in 10.5.2

[kzez1986]

I've installed 10.5.2 from Leo4All ISO (it's new very good prepared ISO without not patching). It installed with no problem but there is no PS/2 mouse and keyboard support in system (in installer it works well). I've noticed that there is no ApplePS2Keyboard.kext and ApplePS2Mouse.kext. Using console from installer program I copied this kexts from CD. But it still doesn't work. I tried repair permission using Disk Utility from installer but it didn't help. When I installed Leopard, to make new kexts load I used kextcache. Would you remind me how to use it and will it work in Leopard? If no, how to load this kexts using installer program from CD (Leopard is my only operating system, and from hard drive keyboard doesn't work so I can't use console from ma installed system. Do I need any other kexts to use PS/2 mouse and keyboard?
