My previous tests confirmed that $MODULES is not empty and contains
well defined space-delimited modules as defined in /etc/default/acpid.
 I've also confirmed that modules.dep checks out so that shouldn't be
the issue but it was worth checking out.

In looking at the /etc/init.d/acpid script from Ubuntu it appears to
solve many of the modprobe issues that I am seeing.  It checks to
ensure the modules exist before loading them and won't attempt to load
modules twice.  Perhaps it's worth merging chunks of their
load_modules() into the Debian script.
