General :: Using Locked Bootloaders To Load Unsigned Kernel

A long time ago, on a 386 far, far away, some people would regularly boot Linux from DOS/Win16/Win32/Win95/etc... using a utility called loadlin. Loadlin would basically grab the system from the short and curlies, and load a target kernel into RAM, and jump directly into, which would effectively be running the kernel in practically the same way as if LILO had loaded it.

Would it be possible to actually make a Linux kernel module which did the same thing? Modules can be loaded at bootup, so it could be configured on a rooted system to load this module, which would effectively jump to a new kernel, throwing the old one out of memory.
