Ok, I'll do that.

Now, I'm still not able to generate the iokitmig32.c and iokitmig64.c  
because I have no idea about how to use mig (darwinbuild does not seem  
to try to generate the C-files by itself). There no man page for mig  
and I also cannot get mig to print out any usage instructions or help  

If I feed it the /Volumes/Builds/Build9G55/BuildRoot/private/var/tmp/ 
xnu/xnu-1228.9.59.root/usr/include/device/device.defs file, it  
generates the following files:


  I have however no idea about with which parameters I should invoke  
it to generate the correct iokitmig32.c and iokitmig64.c files. I also  
don't know where I should put those C and header files (unpack Sources/ 
IOKitUser-388.50.tar.gz, add all generated files to the top level,  
repack and overwrite the previous version in Sources?)
