cmdline ignored

I am trying to kickstart redhat 5.2 64 bit

We have used this %pre script for years and had have no issues.

I am trying to kickstart an HP DL365 G5 but does not like this script

The kickstart machine is running Redhat 4.5

This %pre script worked fine on a G4 with red hat 5.1.

The kickstart always comes up with a GUI to partition the drives

%pre

NEWDEV=`sed 's/.*rootdev=\([^ $]*\).*/\1/' < /proc/cmdline`

echo "##"

echo "## newdev = $NEWDEV"

if test "$NEWDEV" = "cciss" ; then

        DEVICE1="--ondisk cciss/c0d0"

elif test "$NEWDEV" = "ida" ; then

        DEVICE1="--ondisk ida/c0d0"

elif test "$NEWDEV" = "hd"  ; then

        DEVICE1="--ondisk hda"

elif test "$NEWDEV" = "sd"  ; then

        DEVICE1="--ondisk sda"

else

        DEVICE1=""

fi

echo "## kickstart configured with $DEVICE1"

cat > /tmp/parts.ks <<EOPARTS

clearpart --all --initlabel

part /boot --fstype "ext3" --size=128 --asprimary $DEVICE1

part swap --size=2048 $DEVICE1

part / --fstype "ext3" --size=512 --grow --asprimary $DEVICE1

EOPARTS

I have tried this fix but it did not resolve the issue
