just out of curiosity (and cos it's a mad idea :), would it be pheasible to 
use any constant block of 16k?  eg the first 16k of the kernel (or perhaps 
the 16k around some bit of code that would benefit? maybe use lr as the start 
of the 16k, we know we're about to run that code so why not just pre-cache 
it?))  just seems a waste to load in 16k of nothing if we could load 16k of 
code that we're likely to run.
