*Before* swapping out the old disk, add an appropriate scsi_hostadapterN
(N >= 1) alias to /etc/modprobe.conf and then do:
mkinitrd -f /boot/initrd-`uname -r`.img `uname -r`
All should be good then.
IF both the old machine and the new machine have your basic, vanila IDE
disks, then there is no problem.
