I know precious little about NetBSD installation and MIPS Magnum. What I 
wrote above was guesswork. Hence this could be a NetBSD bug or user error.

Does there exist a known-good combination of NetBSD/arc and 
qemu-system-mips64el releases?

If so, I could use that to check for user error or possible NetBSD issue.
