Looking at arch/x86/boot/memory.c I see the snipped:

        } else {
                /*
                 * This ignores memory above 16MB if we have a memory
                 * hole there.  If someone actually finds a machine
                 * with a memory hole at 16MB and no support for
                 * 0E820h they should probably generate a fake e820
                 * map.
                 */
                boot_params.alt_mem_k = oreg.ax;
        }

Could this be what's going on ?  Or am I just grasping at straws ? :-)

cheers,
Chris
