Revision 456

Updates to produce a linuxBIOS table.  Modeled on the earlier
uniform_boot work, but relocated.  You need the new mkelfImage to
use the elf boot format.

Previous tables were updated so I could find both the start and
the end of where they were written in memory.

Minor p4dc6 updates, to disable some debugging code.

The mkelfImage-1.9 is checked in as util/mkelfImage
