Just for the record, I tried a few more experiments with
chainloading NetBSD 1.5.2 using grub, and I can now confirm that
the problem I reported is a NetBSD problem, _not_ a grub problem.

The problem is that when NetBSD is trying to process the "-a" (ask
for root device) option, it hangs later on at the "login:" prompt.

However, the question still remains that when grub is used to boot
the NetBSD kernel directly, why does NetBSD not receive the
correct boot device?  Note that I am not saying that grub does not
pass the correct boot device to NetBSD kernel, this may or may not
be the case, I just don't know.
