I'd do it this way:

- Have a known-good kernel for the new hardware. Preferably as a distro
package so it's easy to install.

- Boot off a live cdrom, or e.g. netboot the system if you know how.
This way the filesystems are not used for e.g. your shell, rsync
binary, shared libraries etc. while it's being overwritten.

- Mount the disk filesystems on a subdirectory. You may want to
repartition and create new filesystems to match the old layout.

- Rsync the backup onto the new filesystems.

- Install the kernel, don't forget to setup grub or lilo or whatever.
Using chroot can be handy here.

- Perhaps tune the /etc/fstab to match the present layout.

- reboot and hope for the best :-)
