"Oh dear," I thought as I read past here.

This justifies my "Oh dear."

I suspect the initrd wasn't create properly.

Try this command, the results should be similar to mine:
[root at potoroo ~]# file -z /boot/initrd-2.6.2*
/boot/initrd-2.6.21-2950.fc8xen.img: ASCII cpio archive (SVR4 with no 
CRC) (gzip compressed data, from Unix, last modified: Sat Oct 27 
09:27:11 2007, max compression)
/boot/initrd-2.6.23.1-42.fc8.img:    ASCII cpio archive (SVR4 with no 
CRC) (gzip compressed data, from Unix, last modified: Fri Nov  9 
09:46:53 2007, max compression)
/boot/initrd-2.6.23.1.img:           ASCII cpio archive (SVR4 with no 
CRC) (gzip compressed data, from Unix, last modified: Sun Nov 11 
09:01:17 2007, max compression)
[root at potoroo ~]#


First, the diagnosis. Assuming yours is a CPIO archive (I'm sure it is), 
you can unpack it like this:
cd /tmp
gzip -dc </boot/initrd-2.6.23.1-42.fc8.img: | cpio <read the man page 
for what goes here>

Have a look at what's come out of it. It should be similar to what I 
have here (this is another way to see what's in it):
[root at potoroo ~]# gzip -dc /boot/initrd-2.6.23.1-42.fc8.img | cpio 
--list | grep ko$
lib/dm-mirror.ko
lib/sd_mod.ko
lib/dm-snapshot.ko
lib/libata.ko
lib/ext3.ko
lib/scsi_mod.ko
lib/dm-zero.ko
lib/jbd.ko
lib/ata_generic.ko
lib/ohci-hcd.ko
lib/ehci-hcd.ko
lib/mbcache.ko
lib/scsi_wait_scan.ko
lib/ata_piix.ko
lib/uhci-hcd.ko
lib/dm-mod.ko
18848 blocks
[root at potoroo ~]# fdisk -l /dev/sda

You need those dm- modules. If they're not there, that's the problem. It 
should be cured by running mkinitrd manually, or you can just copy them 
(from the correct kernel) into that lib directory and recreate the 
archive with cpio and (optionally) gzip. Then, it should "just work," I 
think all those modules get loaded.

Oh, I have a lib64. They don't belong in there.
