Alright, here is where I am with getting to the installer for 10.8.5.
If I go through the same setup I listed before I get stopped at this screen:

I still don't understand what is causing these images to upload upside down. Either way, here is what it stops at:
Pthread support ABORTS when sync kernel primitives misused.

I have narrowed the cause of the error.
If I use the AppleACPIPlatform.kext provided by slayer the system hangs (see picture above).
If I use the default kext that was in the folder to begin with, I get a kernel panic saying ACPI platform driver could not be found (or some other nonsense). I've encountered this error before and got around it by moving to 10.8.4 if I recall. I've tried using other boot arguments to fix this, but it's a no go.
