Cliff Wickman was the guy at sgi running the tests.

To the best of my knowledge he was runing an up to date kexec-tools and
was loading a bzImage.  Of course his initial reaction was where did the
896M limit come from, as he had just updated to a kernel with the limit
a few weeks ago.

YH please talk to Cliff directly.
