If you are literally dumping the whole system backup onto a machine with 
a different controller it can be tricky to make it boot.  Don't panic - 
you can boot your install CD in rescue mode and fix it but it may 
involve building a new initrd image with the right driver.  If the new 
controller works with the old driver, all you need is to get grub 
installed on the new system.
