Of course; you're correct for the platforms with a 2 stage boot.
(first stage boot block loads second stage /boot which parses
arguments from the BIOS/PROM or whatever which loads /netbsd).
This is a lot of NetBSD platforms, including alpha & pmax (not sure
about sgimips), so it won't be a problem there.
As an aside, are there any platforms which load the kernel directly
from the file system from the first stage boot block? (IMHO, the two
stage method is much better)
