Hi Antonio,

What would you like to do? If you just want some arbitrary
page of memory, then look at the 'nopage' example in Rubini,
or ask me and I'll send you some code.

If you want a specific memory location, then you'll need
to claim and ioremap the memory, and again, I can give you
some code.

So, explain a little more and I can help.
