Whether it works or not depends on having the correct hard drive
module either compiled in the kernel or on the initrd. It may
depend on 'how' different the controllers are since some modules
cover several variations.
The kernel and initrd are loaded by bios, then the kernel has to be
able to load the rest of the modules it needs. Obviously it can't
load the hard drive driver module from the hard drive so that has to
have already been conveniently stashed in the initrd image. Other
modules can be loaded from the hard drive so most other hardware
differences will be sorted out on the fly during bootup. You might
have to reconfigure your X setup manually or sort out which network
interface is which, but at least you are up and running while you
do that.
