What about User Mode Linux? http://user-mode-linux.sourceforge.net/
The getting started guide on that page looks pretty persuasive; run
one program, get a whole kernel running fedora in that terminal. It's
said to be useful for hardware development including USB because of
the access it provides:
Not sure of the steps required to get 32bit guest on a 64bit host,
might have to run UML as a 32bit program.
