WARNING: you already have an $CFGFILE file which has not
been generated by update-modules. Debian now uses a new system which
uses multiple files in the /etc/modutils directory. See the manpage
for update-modules for more information on this setup.

Please check all changes you made in $CFGFILE and either
apply them to the provided files in /etc/modutils or add your own
files there. Then run update-modules.

You still have a /etc/cron.d/modutils file. This was used to
remove automatically loaded modules every 20 minutes. However
this is no longer present to prevent problems with kernel versions
2.0 and older and prevent machines from awakening. Removing this
file is strongly encouraged.
