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.

Its reported that a fixed DSDT can help solve panics with Quad Cores. Its just like a file inside the BIOS that contains info about the hardware.
To fix it you would have to extract it from the BIOS, replace it with a fixed one for all cores working and reflash it to the BIOS.
Alternatively you can use a bootloader with DSDT override like Chameleon2, it will let you do the same without risky BIOS reflashing, it just uses a file in the HD as the DSDT table instead of the one from the BIOS, the results are the same. Keep in mind the DSDT is BIOS-specific, up the point it can be different even for same BIOS with a different version (i.e. motherboard x BIOS v1.0 to v1.1).
You should be able to upgrade most bootloaders to Chameleon2 without troubles.
