IOGraphicsFamily UUIDs differ

[CoinCollector]

I'm new to OSx86 and recently got Leopard 10.5.7 running on my PC. Almost everything is working, but when I try to load nVidia-related kexts, such as GeForce.kext and NVDANV40Hal.kext, in Terminal I get this message:
kextload: loaded version 1.5.2 of module com.apple.iokit.IOGraphicsFamily differs from requested version 1.5.2 (UUIDs differ)

So, what can I do about this? Are UUIDs something I can manually change?

Ok, the version I was loading came from the 10.5.5 combo update, and I checked the 10.5.4 update and it also had version 1.5.2 of IOGraphicsFamily. I tried loading that one, and it worked!
