Thanks for all your help,
Its been an absolute pleasure actually ! I've struggled with this thing
on various platforms a number of times and its great to get it working.
For completeness, I've attched my script, ks.cfg and syslinux.cfg files.
The dd.img file referenced in the script is just your standard driver
disk whose modules.cgz file contains drivers for the standard, BOOT, smp
and bigmen kernels.
Here's hoping others will also find useful.
Enjoy !

# ===========================================================================
# ------- So far so good. Now we modify cdboot.img with our kickstart changes.

#
# Step 11: Prepare a work area and some mount points for image tinkering
#
mkdir -p ./work ./work/unpacked.initrd ./work/mntC ./work/mntI

# Step 12: Extract the vanilla cdboot.img from the DVD hierarchy and mount it
#
cd ./work
cp $RHROOT/dosutils/autoboot/cdboot.img .
chmod 644 cdboot.img
mount -o loop cdboot.img mntC
#
# Step 13: Uncompress and expand the vanilla initrd.img, taking it from inside the
# mounted cdboot.img.
#
gzip -cd <./mntC/initrd.img >initrd.unzipped.img
mount -o loop initrd.unzipped.img ./mntI
cd ./mntI
find . -print | cpio -pdm ../unpacked.initrd
cd ..
umount ./mntI
rm unpacked.initrd.img
# -------
#
# Step 14: Copy our custom kickstart file (ks.cfg) into initrd
# The ks.cfg file MUST be copied to /tmp of the initrd.
#
# At a minimum, you need to have included the following line in ks.cfg
# (you can put it pretty much anywhere you like before the %packages
# marker)
#
# driverdisk hda --type=iso9660
#
# Note that the use of 'hda' here means that our new DVD will only
# install on systems where the DVD drive itself is physically
# connected as an IDE primary master. I also found that hda and hda0
# both worked here.
#
cp ../MyPatches/ks.cfg ./unpacked.initrd/tmp/
# -------
#
# Step 15: Reconstruct a new initrd.img using our patched hierarchy.
#
RemakeInitrdFs unpacked.initrd unpacked.initrd.img
gzip -c < unpacked.initrd.img >mntC/initrd.img
# Our modified initrd.img is now safely back inside cdboot.img
# -------
#
# Step 16: Copy our custom syslinux.cfg into cdboot.img to tell the installer that
# we intend to do a kickstart install using the kickstart file we just embedded
# in cdboot.img. Remember that the cd boots by using cdboot.img which is floppy
# image sneakily loaded from the DVD at cold start. The correct syslinux instruction is
# therefore ks=floppy
#
# At a minimum, you therefore need to have done the following to the default syslinux.cfg
#
# CHANGE append initrd=initrd.img lang= devfs=nomount ramdisk_size=8192 vga=788
# TO append initrd=initrd.img lang= devfs=nomount ks=floppy ramdisk_size=32768 vga=788
#
cp ../MyPatches/syslinux.cfg mntC
umount mntC
# -------
#
# Step 17: Put our shiny new custom cdboot back into the DVD hierarchy
#
mv cdboot.img $RHROOT/dosutils/autoboot/
cd ..
#
# Step 18: Leave no trace !
#
rm -r work
# -------
#
# Step 19: Copy the custom driver diskette into the correct place.
# For kickstart to be able to find the drivers we want to use,
# we need to place the CONTENTS (i.e. NOT a copy of the img file!!)
# of the driver disk into the root of the DVD.
