I'd still love any direction on getting the iPC release going as it seems pretty comprehensive. However, I have made some good strides with XxX and iDeneb. It seems like the only missing piece was using cpus=1 at the boot prompt. This, along with:

AppleNforceATA
NforceLan
NVInject or EFI strings
Azalia audio

seems to work, with the obvious downside of 3 cores going unused.

Are there any hints as to how to make the system stable without using cpus=1? I get a panic waiting for a thread (going from memory, I'll post the callstack later).

I read I should try updating my BIOS. I also found a thread suggesting installing Chameleon 2.X and a DSTD package. However, to be honest, I'm not sure what roll the boot loaders play, what boot loader is installed with XxX or iDeneb, etc. Should I be able to just install a Chameleon 2.X package along with the DSTD package without messing up the booting?

Thanks again for all the feedback. This has been very helpful and a nice learning experience.
