The config has all the obvious things (namely, HIGHMEM64G).

Hm, it does look like something is truncating at 4G and wrapping.  The 
question is whether the system really only has 2G available to it, or if 
it's just mis-reporting.
Can you post the full boot log, and the contents of /proc/meminfo?

Thanks,
