Bjorn just informed me that John Marvin was taking a look at this. It looks like we need to make sure the page we're about to look at is valid for the virtual mem map case. And btw, it looks like the contig version of show_mem should be fixed: total shouldn't include non-existant pages (if we add pfn_valid checks to both the discontig and contig versions that should be an easy fix).
