Sort per-module kernel objects (*.ko) by dependency weight. Important modules
are placed in lower addresses. The ``machdep'' module will be always placed
in the lowest.
(At this moment, the order is not exact because dependency information is
incomplete in config files (files.*). Thus ``sysmon_power.ko'' comes lower
than ``machdep.ko'' and/or ``uvm.ko''; but still much better than alphabetical
sort.)
