Different SATA controller, needing a different driver is my guess.

This is not Grub complaining - the kernel is not finding them.

I am not sure how to fix this, unless you can boot from a USB drive.
It looks like the problem is that the new motherboard uses a
different SATA controller. So the driver you need is not in your
initrd. You need to rebuild it. The normal method is to boot from
the install CD/DVD, chroot to where / is mounted, and run mkinitrd.
But in this case, you are going to have to find another way to boot
into the rescue mode.
