SL KP every time i try to use a new Kext

[oochr1soo]

I can get SL to boot no problems if i dont add any Kexts other than those that are recommended. If i try to add one for video or JMicronATA or anything i get KP with the following:

ACPI_SMC_PlatformPlugin::start - waitForService(resourceMatching(AppleIntelCPUPower Management) timed out.

I cant for the life of me figure out what is causing this... Am i missing something?

- I can get sound via VoodooHDA
- No DVD Drive
- No Ethernet (BCM5751)
- No Video (Nvidia Quadro NVS 285)

I'm on a Dell Precision 390 system..

ANy help would be greatly appreciated!

Thanks!
