Whooooa there!

Before we widen the scope of the vimage project to complete 
virtualisation of everything.
How about we get what we have now into the tree? :-)

BTW Marco, you might want to add some comments in vimage.h about how
you see the current framework growing to encompas such things as
dynamically assigned module numbers for kld modules and such so that
when we commit it, there is some sort of architetural guide for the
"thousands of people" who will want to improve it and extend it to
other views of virtualisation.
