When working on a smallish IA32 operating system a few years ago, I
experimented with launching it from a Linux kernel module:
  http://projects.cs.kent.ac.uk/projects/rmox/trac/browser/rmox/trunk/linux26?rev=2271

This appears to work quite well, provided your OS's initialisation
routines do an adequate job of clobbering everything Linux had set
up. I'd imagine the same trick would work on ARM...
