Ummmm....you give ioremap_nocache() a physical address to map, so
you have to know it........Using virt_to_phys() may not give you
the proper physical address, depending upon the platform. I'm working
on a solution for 2.5 that will work. Currently, it is wrapped into
a heavier weight virt_to_bus/phys() but that many not be the right
place.
