Which patch are you using to do this?  Can you send a pointer to it?
What kernel version are you using?  With modern kernels I thought all
that was necessary was:

for i in /sys/class/scsi_host/*/link_power_management_policy; do
    echo min_power > $i
done

Do you have a patch that does better?

Thanks,
