Help with kdump scripts

Hi I am trying hard to append a configuration file like
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
# initrd /initrd-version.img
#boot=/dev/sda
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title Red Hat Enterprise Linux Server (2.6.18-238.el5)
root (hd0,0)
kernel /vmlinuz-2.6.18-238.el5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.18-238.el5.img
i am trying to append a word called crashkernel in the line "kernel /vmlinuz-2.6.18-238.el5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet" as that line is taken from command line parameter.

for eg: if i give -k=crashkernel=512M it should get appended in the above kernel line at the end of the line with double quotes. Please help.
