Theoretically that can be done. The Synology PPCBoot source is available
and you can read there how to create the CRC checksum and how the format
of the environment area on flash has to be.

But I doubt it is worth documenting that for the end user.
Using altboot.img works fine.

You can also flash a new PPCBoot or U-Boot firmware, with all commands
enabled. But I would avoid any risk to turn your device into a brick. ;)

Thanks. I just committed an update for the Synology installation guide.

BTW, I assume you are a native english speaker. So if you find any
form of bad english (syntax, typos, etc.) there, don't hesitate to
tell me about a better formulation.

Exactly.

After that you can remove the serial cable, close the case, and enjoy
your new NetBSD server.

Hmm? It doesn't look any different than the current NetBSD filter setup
to me. The unicast filter is only disabled in promiscious mode. Otherwise
it is always enabled - which strangely doesn't work in our altboot driver.

Great! I assume it is a V200 board? Then there should be no difference
to my TS-101 and it might "just work".

Tell me when I can declare the TS-201 as tested on the sandpoint-page. :)
