   I think you'll find the same limitations with linux-ia64.  IA64
systems aren't typically optimized for such low memory conditions.  The
per CPU area can take a significant chunk of memory, so make sure your
NR_CPUS is configured to as little as possible.  The kernel typically
gets loaded at offset 68MB, making it difficult to go much below where
you are.  Thanks,

        Alex
