If there is nothing in /etc/modules.conf then add these lines there (for
example after the "options" lines), do a "/sbin/depmod -a" and test

# --- Load the hammerfall memory module
pre-install snd /sbin/modprobe snd-hammerfall-mem

This will make sure that the memory module is loaded before the rest of
alsa. Maybe that will be enough. Otherwise you will have to try the
modification outlined before (to /etc/rc.d/rc.sysinit).

There is no difference in memory usage between cold (turn off the
machine) and warm (just reboot) boots.

It does not touch those files. If there are changes that impact them
(and I know of them) I'll include comments with the release.
