How do you get ACPI modules like ac and barrerty to load at boot time?

Add to /etc/rc.local (I'm not sure because I'm in another machine with 
windows only ;-) )

/sbin/modprobe ac
/sbin/modprobe battery

Add the module names to /etc/modules instead.

Add them to /etc/rc.modules, /etc/rc.local, write your own init script,
etc. Code will be added to do this in rc.sysinit in the next build of
initscripts.

I added the following to my rc.local so that I can load modules from
either 2.4 or 2.6:

kern_maj_ver=`/bin/uname -r | /bin/awk -F. '{print $2}'`
kern_ver=`/bin/uname -r`
if [ "$kern_maj_ver" = "6" ]
  then
    /sbin/insmod /lib/modules/$kern_ver/kernel/drivers/acpi/battery.ko
    /sbin/insmod /lib/modules/$kern_ver/kernel/drivers/acpi/processor.ko
    /sbin/insmod /lib/modules/$kern_ver/kernel/drivers/acpi/thermal.ko
    /sbin/insmod /lib/modules/$kern_ver/kernel/drivers/acpi/ac.ko
  fi
if [ "$kern_maj_ver" = "4" ]
  then
    /sbin/insmod ac
    /sbin/insmod battery
    /sbin/insmod fan
    /sbin/insmod processor
    /sbin/insmod thermal
fi

Thinking about it further, I was going to write an initscript that
detected whether acpi=on was passed to the kernel via grub and then load
the appropraite acpi modules for my system. I would think that an
initscript that could be turned off via chkconfig would be the best way
to go, but I'm not expert...

if [ -d /proc/acpi ]; then
   for module in /lib/modules/uname -r/kernel/drivers/acpi/* ; do
         insmod $module
   done
fi

Surely:

[...]
for module in /lib/modules/$(uname -r)/kernel/drivers/acpi/* ; do
[...]

Bah, cut'n'paste ate the backticks. Yes, insert equivalent
shell syntax here...

Hey Guys,

If you take a look at /etc/rc.d/init.d/acpid, you will notice that only 
the 'button' module is loaded at startup.

If you add the other modules (found at /lib/modules/`uname 
-r`/kernel/drivers/acpi) before starting the acpid then everything 
should work quite nicely.

Of course you must specify acpi=on as a kernel option.

That needs to be fixed not to do that since initscripts will load them
all earlier.
