OS X 10.5.6 on an Nforce 680i PC

[nwoolls]

Hey guys, I'm hoping someone can point me in the right direction.

I'm trying to get OS X (iDeneb v1.4) on my PC:

EVGA nForce 680i SLI: http://www.evga.com/products/pdf/122-CK-NF63.pdf
On board audio
On board network
e-GeForce 9800 GTX KO: http://www.evga.com/products/pdf/512-P3-N875-AR.pdf

I've tried both the XxX and iDeneb distributions. I've tried both the AppleNforceATA chipset option and the MCP67 driver. I've tried a few of the networking drivers - forcedeth, NforceEthernet, and NforceLan.

After probably 10 attempted installs, I've seen the introduction to OS X (with welcome in the various languages) once, seen screen corruption another time, and actually booted to the desktop once before the system froze.

At this point, after trying new installs with various chipset options and drivers with iDeneb v1.4, I'm not able to get the machine to boot up after the install at all.

When using the AppleNforceATA chipset option:
The apple boot screen with the spinning circle never stops (left it overnight)
Starting with -v -x again never boots - console output just stops (left over night as well)

When using the MCP67 chipset driver:
The apple boot screen with the spinning circle leads to a kernel panic - tells me to restart in several languages
Starting with -v -x does not boot nor show any descriptive error text - output just stops

See the images here: http://gallery.me.com/nwoolls#100008

The first two images are during verbose mode with AppleNforceATA. The next three are images during verbose boot with MCP67 chipset option.

Any additional suggestions or feedback would be greatly appreciated. I've gotten addicted to OS X on my laptop - I'd love to get this working on my desktop!

Update - I've had another go at it while writing this post. I did an install with just AppleNforceATA and forcedeth. Now I do get a visible error with verbose logging. See the last image in the above gallery. However, I think this may be specific to the forcedeth driver being used.
