To make sure you are loading the _old_ zfs/opensolaris modules, this
should work at the loader prompt:

    unload /boot/kernel/zfs.ko
    unload /boot/kernel/opensolaris.ko
    unload /boot/kernel/kernel
    set kernelname=3D/boot/kernel.old/kernel
    set module_path=3D/boot/kernel.old
    boot kernel.old
