That is a problem that I had thought of, and the easy solution that
came to my mind is boot single-user and then comment out the line in
loader.conf when you /really/ don't need acpi.  This of course assumes
that you don't want to switch your acpi/non-acpi status every other
hour or something.  While that solution is a little inconvenient, it
is not lacking in ability.  If there is a better way, though, I hope
someone speaks up about it.  I know that the loader for me (5.3, 5.1)
has the default with acpi and the #2 disabled.  I really do think that
a better solution.  I'm just not sure how to do it.  You /could/ try
grabbing the 5.3 versions of the loader files, I'm pretty sure that
there is nothing in them that changed between 5.2 and 5.3.
