the files were owned by root:wheel when finished building. I used cp  
to copy to /, at which point I re-grouped it in wheel.

everything there is owned by root:wheel, though I didn't muck with  
anything is System.kext when I installed the kernel, I _only moved  
the mach_kernel. however mark pauley's suggestion that the kernel  
isn't even being seen is leading somewhere. I was using the kswap.sh  
script (http://opendarwin.org/~jpm/naughty/darwin/kswap.sh) to  
install the kernel, but apparently it generates a boot-file variable  
that doesn't work on this machine (g5 dual2.7). if I copy the system- 
installed kernel:

# cp /mach_kernel /mach_kernel.orig
# chgrp wheel /mach_kernel.orig
# kswap.sh --test mach_kernel.orig

this doesn't boot. moving my custom kernel directly to /mach_kernel  
_does boot. I'm currently trying to figure out what an appropriate  
boot-file argument is for a g5.

thanks for all your help.

best,
