Help with restoring IDE image to SATA drive

[FS]

Folks -- My ignorance of all things Linux might be showing with this
posting, but I can't seem to make this work. I have a Linux FC2
machine with an IDE drive which I'm trying to make an image of, so in
case all hell breaks loose we have something we can restore and be up
and running in no time.

The box I tried to restore has a SATA drive. I've already imaged the
SATA drive with the image, but it says "kernel panic".

Where should I start to look for fixing this problem?!? My google-foo
is proving to be worthless for this problem too! I know it's got
something to do with grub, so I'm posting the grub.conf here too.

Any help appreciated!

Thanks,
Faisal

Here are the last few lines before the kernel panic:

RAMDISK: Compressed image found at block 0
Freeing initrd memory: 160k freed
VFS: Mounted root (ext2 filesystem).

Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 00:00

Here's my grub.conf:
