The second statement here isn't entirely true - assuming I understand 
what you meant.  The mac68k port can be installed or upgraded using 
sysinst that is included in the Installation Kernels.  The key is to 
selected the correct Installation Kernel for your system (INSTALL or 
INSTALLSBC) and boot into it with the Booter.  You can copy the 
Installation Kernel to your Mac OS HFS filesystem if you wish.  You do 
not need to un-gzip it before booting it, but you may need to increase 
the memory size for the Booter application.

The Installation Kernels do not understand HFS/HFS+ Mac OS filesystems 
though.  It will process them from a cd9660 CDROM, NetBSD filesystem, 
or via FTP.  You could probably place them on the NetBSD filesystem 
that is your upgrade target, but this will require some manual steps 
that aren't documented.

Contact me offline and I'll try and help you through the process.  All 
I would ask is that you document what you did and make that available 
for others who will follow.

Yes, many times.
