you can use "kmodsyms" to generate a symbol file for an
already-loaded kernel module.
cd to /System/Library/Extensions and do
kmodsyms -o /tmp/IOAudioFamily.syms IOAudioFamily.kext/Contents/MacOS/IOAudioFamily
and then copy /tmp/IOAudioFamily.syms to your debugging
machine.
obviously, you'll need to do this every time you boot
your going-to-panic system, since the addresses in the
symbol file will be different every boot.
