[gentoo-user] hdparm, CONFIG_ATA_SFF and KDE-4.4.4

The title may not make immediately sense, but this is what I have observed.

I switched to CONFIG_ATA_SFF instead of the deprecated CONFIG_IDE.  Up until 
that point I had passed -M 128 to hdparm once and my drive retained the 
settings between reboots and kept quiet.

With the new kernel I noticed that KDE-4.4.4 switches it back to -M 254 and 
becomes noisy as KDE kicks in (when the system settings symbol comes up during 
login).

I tried adding hdparm in the default runlevel and also added:

sda_arg="-M 128"

in /etc/conf.d/hdparm but it doesn't seem to work.  KDE resets it to full 
pelt.

Is there a fix to this?

KDE doesn't do that. It can't.

I hear what you say.  However, ... it does!  O_O

I ran hdparm -iI /dev/sda once from the console and once after I
logged into KDE.  As you can see the KDE command shows:

        Recommended acoustic management value: 128, current value: 254

and

               Automatic Acoustic Management feature set


while the console shows:

        Recommended acoustic management value: 128, current value: 128

and

           *    Automatic Acoustic Management feature set

Also there are some differences at the Security tags at the bottom,
should that make any difference.  Both of the commands were run
without /etc/init.d/hdparm being started at boot time or since.

If I run -M 128 the drive goes quiet and stays so surviving a reboot,
until I login into KDE again. So, if KDE switches of the Acoustic
Management for some reason, there should be some way of asking it not
to?
