There was an intentional backward-incompatible (but still compatible with
the specification) change.  The equivalent command on GRUB 2 would be:

grub> multiboot /netbsd.generic /netbsd.generic -z root=wd0a

First argument is the file being open;  in GRUB Legacy it's implicitly also
the first arg passed to payload, which is less flexible than letting user
specify it.  It doesn't have to be the filename at all, and usually the
payload doesn't need this information.

I'm not sure if this explains your missing word problem, but it sounds like
it could be related.
