At first, one who experiences problem booting into 10.8.2 should try to disable VT-d, if it's enabled in BIOS.

first we need to identify what changed in the appleacpi binary then see if that can be ported somehow to chameleon acpi patching ?
The problem doesn't come from AppleACPIPlatform directly. It's related to VT-d code in IOPCIFamily that Apple had added.
Here's some info.

You can try to boot with :
-v keepsyms=y
Gives more detailed KP.
or another solution:
-v
io=0xffffffff
I vote for keepsyms=y. io=0xffffffff will flood with tech info from time to time, all over graphics mode, while keepsyms will do it's work only on KP (providing you with symbols in addition to addresses).
