Chances are, you have a different hard drive controller on the new
mother board, so the wrong module is in the initrd. (The kernel and
initrd are loaded using the BIOS, so they are not affected.) All you
need to do is boot with the rescue disk, chroot to your file system,
 mount /boot if it is a separate partition, and run mkinitrd for
your kernel.
