After a bit more investigation. the livecd-tools package in F9
(017.1-1.fc9) can only build F9 correctly, and the problem boils down
to incorrect placement of the .ko files in the initrd. Here is how to
repro with F9 vs F7. In my testing, F8 shows the same problems.

1 - Take the fedora-minimal.ks file and replace "rawhide" with
'fedora-9', 'fedora-7' - as follows:

--8<----8<----8<--
lang en_US.UTF-8
keyboard us
timezone US/Eastern
auth --useshadow --enablemd5
selinux --disabled
firewall --disabled
part / --size 1024

repo --name=released
--mirrorlist=http://mirrors.fedoraproject.org/mirrorlist?repo=fedora-9&arch=$basearch

%packages
@core
bash
kernel
passwd
policycoreutils
chkconfig
authconfig
rootfiles

%end
--8<----8<----8<--

2 - Build one minimal Liveimage for each. The image should boot to a
login prompt - though it will not allow logins as no root pw has been
set.

3 - Boot the images with qemu -m 512 --cdrom <path-to-iso> -- the F7
iso will panic

4 - mount -o loop both ISOs, in my case in /tmp/f7 /tmp/f9 and extract
the initrd in each

5 - find initrd-7 initrd-9 -type f -name '*.ko'
initrd-7/lib/mbcache.ko
initrd-7/lib/sr_mod.ko
initrd-7/lib/msdos.ko
initrd-7/lib/ext3.ko
initrd-7/lib/ehci-hcd.ko
initrd-7/lib/uhci-hcd.ko
initrd-7/lib/pata_pcmcia.ko
initrd-7/lib/mmc_block.ko
initrd-7/lib/jbd.ko
(...snipped...)
initrd-9/lib/modules/2.6.25-14.fc9.i686/pata_jmicron.ko
initrd-9/lib/modules/2.6.25-14.fc9.i686/ata_generic.ko
initrd-9/lib/modules/2.6.25-14.fc9.i686/pata_qdi.ko
initrd-9/lib/modules/2.6.25-14.fc9.i686/sata_vsc.ko
initrd-9/lib/modules/2.6.25-14.fc9.i686/sata_sil24.ko
initrd-9/lib/modules/2.6.25-14.fc9.i686/pata_hpt366.ko

Additionally, I have a F7 liveCD built elsewhere (with an earlier,
patched version of livecd-tools) that boots successfully - the initrd
of that liveCD looks like
find initrd-7-good -type f -name '*.ko' | head
initrd-7-good/lib/modules/2.6.23.1-21.fc7/pata_jmicron.ko
initrd-7-good/lib/modules/2.6.23.1-21.fc7/ata_generic.ko
initrd-7-good/lib/modules/2.6.23.1-21.fc7/pata_qdi.ko
initrd-7-good/lib/modules/2.6.23.1-21.fc7/sata_vsc.ko
initrd-7-good/lib/modules/2.6.23.1-21.fc7/sata_sil24.ko
initrd-7-good/lib/modules/2.6.23.1-21.fc7/pata_hpt366.ko
initrd-7-good/lib/modules/2.6.23.1-21.fc7/mbcache.ko
initrd-7-good/lib/modules/2.6.23.1-21.fc7/sata_sx4.ko
initrd-7-good/lib/modules/2.6.23.1-21.fc7/pata_serverworks.ko
initrd-7-good/lib/modules/2.6.23.1-21.fc7/sr_mod.ko

I am not sure why this is happening, but I keep working on this.
