You will find an updated version of this patch with LPAE support. I've
tested with and without LPAE selected.

Just a rectification, in fact I managed to build in both case, and to run
only without LPAE support. I didn't have the support for LPAE yet. I was
surprised that it worked out of the box, but in fact I tested the wrong
kernel! I realized this this morning.

Ok, please keep me updated with how you get on. I can't shake this nagging
feeling that the memory-mapped interface is restricted to 32-bit addresses,
which is why the XP has the option to treat the L2 as an inner-cache...
