But I don't see anything like a physical address there:

  /sys/devices/system/memory/memory2:
  -r--r--r-- 1 root root 4096 2008-07-21 15:45 phys_device
  -r--r--r-- 1 root root 4096 2008-07-21 15:45 phys_index
  -rw-r--r-- 1 root root 4096 2008-07-21 15:45 state

(on a PPC64 machine where SUSE kernel has that interface enabled by
default).
