Seems to work just fine.  I tested by booting, toggling through the
different kernel choices (/boot/kernel/kernel /boot/kernel.old/kernel)
and both worked correctly.

(Although I uncommented the "include /boot/beastie.4th" line too.)

Well, I'd probably be in support of this change - it sure beats having
to interrupt the normal boot sequence and typing:
    unload
    load /boot/kernel.old/kernel
    load /boot/kernel.old/opensolaris.ko
    load /boot/kernel.old/zfs.ko
    boot
When I need to get back to the prior version of the kernel.
