Bootloader drops to dracut shell after FC17 upgrade

After a long struggle with the install DVD and Anaconda (posted elsewhere in this forum) I gave up and upgraded from FC16 to FC17 using yum. After a few issues I can boot up OK except that if I select the FC17 kernel (3.4.4-5.fc17) the bootloader gives me warnings about
unable to open '$devnode'
Unable to process initqueue
/dev/mapper/VolGroup00-LogVol00 does not exist
before dropping to the dracut prompt. (Screenshot attached as .PNG.)

I am using LVM and have /, /usr, /var and /usr/local on separate LVs, though this has not caused major problems before. I can boot to the FC16 kernel (3.3.7-1.fc16) without problem, though I do get a kernel panic when I shut down.

Dracut is 018-78.git20120622.fc17 - this is the only package version for this, though there are quite a lot of FC16 and FC17 duplicate packages elsewhere. I had to rebuild initramfs a few times and edit grub.cfg to get even this far - the upgrade seems to leave a few things out. This is the relevant part of grub.cfg
        set gfxpayload=keep
        insmod gzio
        insmod part_msdos
        insmod ext2
        insmod lvm
        set root='(hd0,msdos1)'
        search --no-floppy --fs-uuid --set=root a2a7bbe2-e3ea-4982-847e-c4ae9f51ed77
        echo 'Loading Fedora (3.4.4-5.fc17.x86_64)'
        linux   /vmlinuz-3.4.4-5.fc17.x86_64 root=/dev/mapper/VolGroup00-LogVol00 ro quiet SYSFONT=latarcyrheb-sun16 rhgb KEYTABLE=uk rd.luks=0 LANG=en_US.UTF-8

        echo 'Loading initial ramdisk ...'
        initrd /initramfs-3.4.4-5.fc17.x86_64.img
It is as if the bootloader can't see LVM volumes under FC17 - though it clearly can in FC16.

Any ideas or suggestions?
