You're loading the NetBSD kernel directly with GRUB.  That breaks ksyms,
because GRUB hasn't been taught how to boot a NetBSD kernel posterior to
the 1.4 release (and thus gives bogus information about the layout of
the ELF sections).

You have to chainload the NetBSD bootloader.

The Multiboot stuff works just fine, but AFAIK it's not available on
netbsd-3.
