What is gzboot used for then? What's it's purpose?
According to your former email you cat gzboot "inserting" it to to the image:
$ nbmake-evbarm-el && cat /path/to/gzboot netbsd.bin.gz > /tftpboot/image
What actually happens there?

The kernel I used was a gziped netbsd image:
# /usr/obj-xcale/sys/arch/evbarm/compile/IXDP425]> file netbsd
netbsd: ELF 32-bit MSB executable, ARM, version 1 (ARM), statically linked,
So you mean I should rather use netbsd.bin ?
I actually did not notice/know there was a .bin kernel image in the compile

Does the rest look OK ? The partition table of my redboot and the memory
address I chose to use?
And thanks a lot for your answer Allen.
