                      5: This can be extremely useful for development and testing.

1.4     ! ryoon       8: QEMU emulates ARM's Integrator/CP board. You can run NetBSD under it.
        !             9: Older NetBSD had the problem to run under QEMU's emulated Integrator/CP
        !            10: board.
        !            11: Sergio L√≥pez had created the patch for NetBSD current and had posted
