Such a kernel (with init program) exists. It is called kexec-loader:
  http://www.solemnwarning.net/kexec-loader/


kexec-loader is a Linux based bootloader that uses kexec to start the
kernel of
your choice. It fits on a 1.44MB floppy, supports most block
devices supported
by Linux and is easy to use. kexec-loader supports
reading GRUB
configuration files, this allows kexec-loader to be used
as a drop-in replacement
for GRUB by merely setting the GRUB
installation path. 
kexec-loader is aimed at people who wish to boot Linux or any other kernel
supported by multiboot off
a device which the BIOS does not support.
For example, you may wish to use it to boot from a CD-ROM
drive or USB Hard
Disk that the BIOS can not boot from for whatever reason.
