i didn't write the original version of this, but you might find it
useful. use it as normal system startup script (how to do this varies
depending on your distro, but probably involves /etc/rc.d/init.d)
#!/bin/sh
case $1 in
start)
setpci -v -s "*:*.*" latency_timer=b0
# Update this one with the device you want to optimize
setpci -v -s 04:01.0 latency_timer=ff
esac
exit 0
