0xc0100000 is the kernel virtual address of the load address, which the 
NetBSD boot loader compensates for.  I suggest that, instead of 
changing the kernel link address, you adjust the command you issue to 
RedBoot to load the S-record image (you can also load a flat binary 
image with RedBoot, which might be a lot faster).

That's because you linked the kernel at the wrong address in an effort 
to get RedBoot to load it.  Follow my suggestion above, and you should 
be fine.
