XXXX is not compatible with its superclass, 13IOAudioEngine superclass changed?

I've seen this posted, but nothing has helped me as of yet.

I am trying to compile a KEXT that is basically the same thing as the PhantomAudioDriver.  Heck, I even tried compiling that and it didn't work.  Here's what I get from kextload -t

kextload: extension PhantomAudioDriver.kext/ appears to be valid
kextload: loading extension PhantomAudioDriver.kext/

udioEngine is not compatible with its superclass, 13IOAudioEngine superclass changed?
kextload: a link/load error occured for kernel extension PhantomAudioDriver.kext/
load failed for extension PhantomAudioDriver.kext/
 (run kextload with -t for diagnostic output)


Now i've seen stuff all over about compiling against the 10.4.0 sdk and I am.  I'm using Mac OS X 10.4.8 on PPC with Xcode 2.4.  I know it's an incompatibility betweeen the IOAudioEngine in the headers and the IOAudioEngine in the running kernel.  Problem is, I have no clue how to reconcile the issue.  *ANY* guidance, docs, or anything that someone can offer would be of immense help.
