I added the following lines to my /etc/rc.d/rc.local file, and it sets the
defined latency ($LAT) to any SATA and IDE pci devices (as matched by the
egrep pattern.

I use HEX value "b0" as stated in a link that was posted to the mvpmc
mailing list.

LAT=b0
for DEV in $(lspci|egrep "(SATA|IDE)"|awk '{ print $1 }')
do
    setpci -v -s $DEV latency_timer=$LAT
done
