Umm ... well, one thing you might do is boot the new kernel into 
single-user, manually NFS-mount a fileserver containing the tarballs, and 
then use `tar --unlink -zxvpf /path/to/tarball.tar.gz' from `/' to 
install them ... note that tar and gzip are statically linked to help 
with this.

You might also consider netbooting the system from another machine and 
then untarring the snapshot onto the disk...
