The normal way to cure this problem is

1. Boot from a live CD (Knoppix, et al)
2. Mount your existing / (and /boot as well, if you have a separate
/boot). You may also need to mount /proc on top of the eisting /.
3. chroot to the mounted / parition.
4. Rebuild your initrd using your distro's tools.
5. exit from chroot and umount /proc (if mounted) /boot (if mounted), and /
6. Cross your fingers and reboot.

All of this presumes that your distro's kernel supports the new sata controller.

hth,
