Can anyone see a problem with the methodology in the script below for testing 
the effect of the sd_drive and sd_idleclk parameters on TTFF? Am I doing 
something stupid like setting the wrong parameters or values? 

#!/bin/sh
PASSES=10
TTFF=""

get_ttff() {
  echo "1" > /sys/bus/platform/devices/neo1973-pm-gps.0/pwron
  TTFF=`(time grep "GPRMC,[0-9\.]*,A," -m 1 /dev/ttySAC1) 2>&1 |grep real`
  echo "0" > /sys/bus/platform/devices/neo1973-pm-gps.0/pwron
  echo $DRIVESTRENGTH $IDLECLK $TTFF
  sleep 20
}

echo d i time
until [ $PASSES -eq 0 ]
do
  for DRIVESTRENGTH in 0 1 2 3
  do
    for IDLECLK in 0 1
    do
      #echo testing drive strength $DRIVESTRENGTH and clock idle $IDLECLK
      echo $DRIVESTRENGTH > /sys/module/glamo_mci/parameters/sd_drive
      echo $IDLECLK > /sys/module/glamo_mci/parameters/sd_idleclk
      get_ttff
    done
  done
  PASSES=$(($PASSES-1))
done
