the recent vm change uncovered a long standing latent pseudo-bug where the local and ioapic memory window were mapped into kernel space via create_area(), not map_physical_memory() like it should be. create_area() used to work fine, but now it's a big more picky about mapping memory it can't get a vm_page to (like stuff outside the range of RAM).
