This is very similar to how the MIPS ports does things.  Since the TLB
structure of the AVR32 is similar to MIPS, maybe looking at how it
does its thing might be helpful.  Of course, this conclusion was
reached by just glancing a the AVR32 spec some months ago, so some
discretion might be needed :-).
