There has been a bit of a discussion about this the last couple of
days on netbsd-current list - check gmane if you want to have a look.

This is my menu.lst file (the first four lines do not work with the
version of grub from pkgsrc - they are from a Solaris setup, but don't
cause trouble here):

You get this, if you have kernel --type=3Dnetbsd, as in my entry No.3 .
The parameters do not get passed if MULTIBOOT is disabled in the
kernel.

The easiest is to use the entry No.1 - chainload. The NetBSD kernel
does not have any knowledge about grub.

My default entry, as you can see, happens to be No.2 - this requires

options         MULTIBOOT       # Multiboot support (see multiboot(8))
options         MULTIBOOT_SYMTAB_SPACE=3D1048576

in the kernel, you get:

...
 NetBSD 3.99.20 (M0) #2: Sat May 27 00:54:24 BST 2006
        root@maggie:/usr/src/sys/arch/i386/compile/M0
multiboot: Information structure flags: 0x000007e7
multiboot: Boot loader: GNU GRUB 0.97
multiboot: Command line: /netbsd console=3Dpc root=3Dwd0a
multiboot: 638 KB lower memory, 523200 KB upper memory
total memory =3D 511 MB
avail memory =3D 495 MB
...

multiboot messages, but unfortunately there may be some side effects -
as happened to me a few days ago - if the kernel had 'pseudo-device
ksyms', then netstat would not work. (One certainly could ask more
questions as to what else doesn't work...)

I guess, use chainloader.
