Please read the post I posted yesterday on this.  Oh go on, I'll
quote it:

--
Caveat - see earlier discussions here about the seeming
unpredictability of module loading where duplicates exist in
/lib/modules/<kernel>/: the default 0.8 one is install in
kernel/drivers/acpi, and the default installation path for 0.11 goes
into acpi/.  On the face of it this isn't a problem, as modules.dep
specifies (for me, in FC4) the acpi/ one first, so loads it when I
modprobe - but as someone else pointed out, if the
kernel/drivers/acpi one is present, it gets loaded by insmod very
early on in /etc/rc.d/rc.sysinit (and insmod of course ignores
modprobe.conf options).

The issue will probably be similar for your distro.

You also need to say which keys you're enabling via a mask, e.g.

# echo 0100 > /proc/acpi/ibm/hotkey

or the equivalent hex code.  Described in the README.  If this
doesn't work, press keys and watch /var/log/acpid for codes.
