Your way is better.

Conceptually, your way makes more sense.  But some people prefer not to 
muck around with existing files, if possible, and make all of the 
changes in the new file that you have to create anyway.  Either way is 
ok with me.

You don't actually need to put the NetBSD kernel in flash, though that 
is certainly one option (and one that I would like to explore further).  
Another way is:
1. Create an ext2 slice (for Linux or just for booting) that U-boot can 
read and a NetBSD slice that you use to install the world on.
2. Install  NetBSD to the disk.
3. Put the kernel on the ext2 slice and change the U-boot boot string 
(bootcmd) to point to the NetBSD kernel instead of the Linux kernel 
(something like:
bootcmd=ide reset; ext2load ide 0:1 0x8000 /netbsd.bin-KUROBOX_PRO; g 0x8000
- but I'm doing that from memory).  If you can't figure out how/where, 
I'll have to look back through my notes.  Mine is set right now to boot 
using tftp using the boot string:

bootcmd=tftp 0x8000 netbsd.bin-KUROBOX_PRO; g 0x8000

This is all still not perfect, since I think you need to use Linux to 
create the ext2 slice, but closer.
